You might also remember that a couple of those laptops managed to stand out from the crowd — including Hewlett-Packard’s Envy Spectre 14, which goes on sale today.

Showgoers were abuzz about the glossy, Gorilla Glass-coated Spectre — despite the fact that at almost four pounds, it weighs slightly more than some other ultra-thin, Intel-driven Ultrabooks. At $1,399, it’s 20mm thin with a 14-inch screen, supports up to 256 gigabytes of storage and boasts up to nine and half hours of battery life. It also has a backlit keyboard and “proximity sensors” that light up when a user is approaching the laptop and, naturally, it has HP’s Beats Audio built in.

Another notable feature is that it incorporates near field communication technology, like the kind we’ve been seeing in mobile phones for quick, one-tap payments. HP says that the NFC tech in the Spectre, which is built into the left side of the palm-rest area, will be compatible with NFC-enabled Android phones.

So, how will it work, exactly?

After downloading the HP Touch to Share app from the Android Market, Spectre owners that have an NFC-enabled Android phone will be able to transfer URLs from the Android phone to the Spectre using NFC. For example, if you’re browsing the Web on your phone, you can then tap your screen and transfer that page to the laptop’s Web browser.

You can’t currently share photos, music or other media this way, an HP spokesperson confirmed. And while NFC is often associated with e-commerce, that’s not the usage we’re talking about here. (Since the laptop isn’t a payment terminal, you can’t, for example, browse Amazon.com, see something you’d like to buy, open up a wallet app on your phone and tap the screen with your phone to pay.) But it is a way for smartphones to “speak to” the laptop without using wires or cloud apps.

The NFC market for mobile is expected to grow dramatically over the next few years, with IHS iSuppli forecasting 544.7 million NFC-equipped cellphones to be shipped by 2015 (from 93.2 million last year); it’s likely that we’ll see this tech coming to more devices outside of mobile phones and tablets.

Nintendo, for one, recently said it plans to bring NFC to its long-awaited Wii successor, where it will be used to transfer gaming data.

So HP and Lenovo have added some features to their Ultrabooks to set them apart from all the ultra-noise.

Lenovo's IdeaPad Yoga

The Lenovo IdeaPad Yoga is named as such because of its flexibility. The 10-finger touchscreen has a full range of motion at the hinge, so when fully folded, the laptop turns into a 13.3.-inch tablet. And it can be propped up in tent mode — or, in this case, downward dog. I could see this being useful for entertainment viewing at home, as well as in small spaces, such as on an airplane.

Other laptops have shown this range of motion before — remember the Dell Inspiron Duo? — but adding this feature to a super-slim, touchscreen Windows 8 laptop is a nice touch.

The Yoga’s cover is solid aluminium; it measures 16.9mm thick and weighs 3.1 pounds. It is, of course, powered by an Intel Core processor, with 8 gigabytes of RAM and a 256GB solid-state drive. Lenovo claims the battery lasts up to eight hours.

Since the IdeaPad Yoga runs the upcoming Windows 8 operating system, the laptop likely won’t be available until the second half of the year. A representative for Lenovo said the company hopes to price it around $1,300.

Gorilla Glass is what makes the HP Envy Spectre 14 stand out. The ultra-thin, chemically strengthened material is what coats the exterior and the wrist rest of this laptop, giving it a sleek, reflective look — albeit one that needs to be wiped with a cloth pretty frequently.

HP's Envy Spectre 14

Yesterday at CES, someone lamented to me, regarding the Envy Spectre 14, “But it’s so heavy.” Weighing in at almost four pounds, the Spectre is a bit heavier than other Ultrabooks, but for comparison’s sake, the 13-inch version of the “regular” HP Envy notebook is just about the same, at 3.68 pounds.

The Spectre is 20mm thin, has a 14-inch screen and Intel Core processors, and supports up to 256GB of storage. It also boasts nine hours of battery life, versus Lenovo’s eight. The Spectre also has a backlit keyboard and proximity sensors which detect when a user is approaching the laptop and light up the keys in advance. And it has HP’s Beats Audio built in.

Another interesting feature of the Spectre is that it’s NFC-enabled; theoretically, users can share data from an NFC smartphone by tapping the phone against the Spectre.

The HP Envy Spectre is expected to launch in early February, and will cost around $1,399.

Neither of these Ultrabooks have DVD slots, but the HP Envy Spectre 14 has an expandable Ethernet port, USB 3.0, HDMI and Mini DisplayPort, while the IdeaPad Yoga has USB 2.0 and 3.0 ports, an HDMI port and an SD card slot.

A fun side note about the HP Envy Spectre 14: A company representative says HP actually first displayed a prototype of this Ultrabook last fall, during New York Fashion Week. But it was a “bejeweled” version, with Swarovski crystal designs by Marchesa, and fashion-focused reporters barely batted an eye at the thing. Who knew they were missing one of this season’s biggest CES trends?

The company is announcing both a consumer model, the IdeaPad Tablet K1, and a more business-oriented product, the ThinkPad Tablet. The former features support for Netflix and a range of included entertainment software, while the latter features pen support and an optional plug-in keyboard dock. Both products have 10-inch screens, start at $499 and will go on sale in August, with pre-orders being taken starting on Wednesday.

“Tablets are extremely personal technology devices,” Senior VP Liu Jun said in a statement. “That’s why we’ve created a family of tablets that has something for everyone, including entertainment-friendly features and content for consumers, or business-friendly features to enhance productivity for professionals as well as security and manageability for IT managers.”

The IdeaPad includes 32GB of memory, while the ThinkPad Tablet comes with 16GB of memory and includes a variety of features aimed at offering business-level security and reliability. The initial ThinkPad model is Wi-Fi only, but Lenovo said 3G models are also in the works and should come shortly after the first ThinkPad Tablets hit the market.

Lenovo is planning its own Lenovo App Shop to provide access to apps customized and tested for its hardware as well as to allow businesses to serve up programs privately to their users.

The company is just the latest big name announcing plans for an Android tablet. Sony is also hoping to prove that taking one’s time can pay off, with its first Android tablets — the slate-shaped S1 and clamshell S2 — not expected until this fall.

The question is just how big the market is for Android tablets, at least at this juncture, with few apps available and a number of hardware makers already selling products, including Motorola, Acer and Samsung, to name just a few.

Lenovo also has plans for a new Windows 7 tablet, the IdeaPad Tablet P1, due in the fourth quarter.

I’ve been testing one of these new IdeaPads, a small, thin model called the U110, that’s sized to be ideal for travelers. It looks nothing like a classic black ThinkPad. It even comes in red, has swirls etched into its case, and can supposedly log you in by recognizing your face using its built-in camera.

At the same time, I’ve been trying out another similarly sized little laptop, the U2E from Asus (23571.TWO), a Taiwan-based company whose products are relatively new to the U.S. This computer has its own distinctive design: It’s clad in real leather. It also has a camera, and it can be ordered with one of the new solid-state drives, which have no moving parts, instead of a hard disk.

Both of these small laptops are subnotebooks, meaning they weigh 3 pounds or less. Like many subnotebooks, they have small 11-inch screens and somewhat cramped keyboards. And, like most subnotebooks, they are costly — an $1,899 starting price for the Lenovo and $1,999 for the Asus.

Each can only be ordered with Microsoft’s (MSFT) Windows Vista operating system, which means you can practically walk your dog in the time it takes them to start up. Each has a standard battery so wimpy that it provides poor battery life, so both companies throw in bigger batteries that provide decent power, but make the computers larger and heavier.

I wish I could recommend a clear winner between these two contenders, but both are mixed bags. The IdeaPad is lighter, thinner, and has a slightly faster processor. The Asus has a built-in DVD drive, while the Lenovo’s is external. The Asus also has the new, faster “N” type of Wi-Fi networking, while the IdeaPad is stuck with the older, slower “G” type.

Lenovo’s small, thin IdeaPad model called the U110.

The IdeaPad has two big flaws, in my view. First, it has blown the biggest advantage of its sibling, the ThinkPad: a great keyboard. The IdeaPad keyboard has huge, flat keys with slick, shiny surfaces and almost no space between them. I found typing difficult with this setup. I asked two people who are faster typists than I am to try it: One liked it, one hated it. The IdeaPad also dispenses with the TrackPoint, the little pointing stick for moving the cursor that many ThinkPad lovers revere.

By contrast, the Asus U2E keyboard, while nothing to write home about, is more conventional and more usable, with traditional tapered keycaps that provide better key separation. The mouse buttons underneath the touch pad on the Asus, while thin, were sturdier than the ones on the IdeaPad, which had a cheap feel to me.

The second big flaw in the IdeaPad is its most hype-worthy feature: face recognition, which is meant to spare you the need to type in a password to log in. In a dozen tests, it recognized me only twice. I asked my wife to try it, and it never once recognized her. It did recognize a colleague successfully, but we tried it only once with her.

The Asus’s biggest flaw is its solid-state drive. It adds $700 to the price, for a total of $2,699, but is only 32 gigabytes in size, tiny by today’s standards. To compensate, Asus throws in an external hard disk, but that’s an inconvenient solution.

You can order the Asus with a standard 120-gigabyte internal hard disk for the $1,999 price, but that’s still $100 more than Lenovo charges for the IdeaPad with the same sized drive.

Each machine has three USB ports, a video-out connector, a slot for camera memory cards, and an ExpressCard slot, typically used for cellphone modems. Neither has a built-in cellphone data modem. The Asus has three gigabytes of memory, the Lenovo just two.

In my tough battery tests, where I turn off all power-saving features, turn on the Wi-Fi, and keep music playing constantly, the Asus got about 1.5 hours and the Lenovo a miserable one hour and three minutes. This means that, even with a more normal usage pattern, you’d be lucky to get two hours out of the IdeaPad and 2.5 hours from the Asus.

With the included bigger batteries, the IdeaPad clocked out at three hours and 10 minutes, which means you could probably stretch it to over four hours with more normal use. The Asus’s bigger battery delivered an excellent five hours and 29 minutes in my test, which points to nearly seven hours in more normal use. Asus says it has tweaked its machines to improve battery life somewhat.

However, while the jumbo battery on the IdeaPad barely protrudes from the machine, and keeps the weight under three pounds, the one on the Asus U2E is so huge it looks like a tumor and pushes the weight to 3.4 pounds, well above the subnotebook cutoff.

If you’re a frequent traveler, both of these models are worth considering, but each has its own flaws.
