Hey Kids! Max Out Your Credit With Apple’s Back-to-School Season Refresh!

That telltale “We’ll be back soon” sign appeared on Apple’s online store early Tuesday morning, and when it disappeared a few hours later the company had refreshed a number of its product lines and debuted some entirely new gear as well. Announced this morning: new Mac Pro desktops, new iMacs, a 27-inch LED Cinema Display, an eco-friendly battery charger and a multitouch Magic Trackpad.

Apple’s (AAPL) iMac and Mac Pro lines now offer faster Core i3, Core i5 and Core i7 processor options, with the last available in a $4,999 configuration with a full dozen Intel Xeon cores. IMacs cost between $1,199 and $1,999.

The long-awaited 27-inch LED Cinema Display boasts 2560 x 1440 resolution and a 16:9 aspect ratio. Optimized for Apple’s latest hardware, it features a built-in iSight video camera, microphone and speakers, 3-port USB 2.0 hub, and a universal MagSafe connector for charging up a MacBook. Price: $999. It ships in September.

Finally, there are the peripherals: An Apple Battery Charger that senses when its batteries are fully charged and adjusts its power usage accordingly ($29.00 with six rechargeable AA NiMH batteries), and a $69 Magic Trackpad that adds to the desktop the same gesture commands supported by the iPhone and iPad.
