That was way back in October, though, and since then, production delays have slowed the Nook’s entry into the market. The devices were hard to buy online for the 2009 holiday season. And they haven’t been available at all in stores–you could talk to a store rep about one, and if you were lucky, you got to fondle one, but that was it.

Now Barnes & Noble (BKS) says that starting Wednesday, the $259 device will be available in the “majority” of its 775 U.S. stores.

Better late than never. But not a lot better.

Barnes & Noble’s problem, of course, is that in the last couple weeks, the e-reader market has been completely redefined, at least among the chattering classes: It’s now Amazon’s (AMZN) Kindle vs. Apple’s (AAPL) iPad.

It’s still theoretically possible for Barnes & Noble–and Sony (SNE), for that matter, as well as Plastic Logic and the other would-be competitors–to elbow their way in, since the e-book market itself is still pretty young.

But they had better move very, very fast. Even if they offer devices that are as good or better than Apple’s or Amazon’s, they’ll be hard-pressed to combat the other huge advantages those two have over the rest of the pack–established e-commerce relationships with a huge customer base.

“On the new online Microsoft Store, we’ve added a bunch of new products, including Windows 7 PCs as well as select 3rd party software and accessories,” Trevin Chow, senior lead program manager for Microsoft Store, said in a blog post announcing the move. “And let’s not forget a ton of gaming products that have been added including a bunch of the top selling Xbox 360 titles.”

Interesting. Not exactly sure what the upside is to selling PCs online when you don’t make them. It’s not like Microsoft (MSFT) will be offering a better experience than, say, Best Buy (BBY), HP (HPQ) or Dell (DELL). And an online outlet doesn’t afford the company the same opportunity to cultivate the “Microsoft Experience” it’s clearly going for in its brick-and-mortar outlets. So why bother?

A unified experience online and off, I suppose. And, if the infrastructure is in place to sell through one channel, why not sell through both? Of course, the downside is that if you don’t execute well, you risk giving customers another lousy experience with which to associate your products.

The latest institution to realize this–Bank of America (BAC) which, according to The Wall Street Journal, plans to close up to 10 percent of its 6,100 branches across the country over the next three-to-five years. It’s not yet known when the closures will begin or exactly how many locations will be closed. BofA says only that “Our vision is the network will be managed downward over time.”

About time too. With fewer and fewer consumers banking at their local branches and remote deposit capture an easy matter via ATM, it seems foolhardy to maintain them.

“They are not economically viable,” Rochdale Securities analyst Dick Bove wrote in a recent note to clients. “The branches are likely to be closed for three reasons: a) branch economics are changing; b) the need for positioning has been reduced; and c) the fear of regulation suggests closing branches now makes sense.

“When America was building new houses in the millions,” Bove continues, “it was creating new neighborhoods. Banks competed with each other to get branches into the new communities in the choicest locations. Branches were often built in supposed choice locations just to keep the competitors out. This strategy has now been abandoned. Many of the new communities have been abandoned. These branches need to be abandoned.”

I suppose when your financial statements look like Blockbuster’s, I suppose you cling to life however you can (Blockbuster shares have fallen about 80 percent over the last 12 months). And so, beginning in the second half of 2009, the company will make its Blockbuster On Demand service available to TiVo subscribers. The agreement also calls for Blockbuster’s brick-and-mortar stores to sell TiVo DVRs. “We are excited to be teaming with TiVo, the company that created the DVR, to make Blockbuster’s entertainment content readily available to their millions of subscribers,” said Blockbuster CEO Jim Keyes. “Ultimately, our vision is to work with TiVo so that their subscribers can access movies not only through our On Demand service but also from our stores and through our by-mail service as well.”

For Blockbuster (BBI), the deal is a means of capitalizing on the rising popularity of on-demand video. But to really do that effectively, the company needs alliances with more electronics manufacturers than just TiVo (TIVO). After all, the DVR pioneer isn’t in the greatest of health these days. And Netflix (NLFX) already delivers online video to TiVo and PCs, Macs, Xbox 360s, and selected LG and Samsung Blu-ray players as well. Clearly, Blockbuster is as late to on-demand as it was to DVD-by-mail.

Seems the econalypse and the absence of a “must-have product” really played havoc with spending during our annual consumer binge. Said Baker, “Not only was there not a really hot product, not only did the economy tell people that they shouldn’t buy stuff, but the stuff I have [is] more than good enough in most cases.”

Yup, more of the same: Holiday sales from Nov. 1 through Dec. 19 are down one percent compared to the same period in 2007. Which is right in line with comScore’s (SCOR) prediction of flat online sales for the holiday.

If you’d like a rosier glow to these numbers, comScore tries to oblige, by noting that average online spending between Thanksgiving and Dec. 19 is actually up five percent per day. But since there are fewer days between Thanksgiving and Christmas this year compared to previous years, that won’t help retailers’ top or bottom lines.

What are people buying on Amazon (AMZN) and other electronic storefronts? Fewer flat screen TVs, ComScore says, either because promotional discounts have tapered off or because those who need a 42-inch LCD on their walls have already got one.

Meanwhile, I’m not sure what constitutes an online “Sports and Fitness” purchase, but ComScore says people have been making many more of them this year, because the category is up 31 percent. Music, movies and videos are much more familiar, and much less popular. Sales are down 24 percent, which mirrors what Best Buy (BBY) said about its brick and mortar sales for the same goods earlier this month.
