Barnes & Noble's Nook Color just In terms of hardware the Nook Color is certainly not the most powerful tablet out there: It packs a Texas Instruments ARM Cortex-A8 800MHz processor, 8GB of internal memory plus a MicroSDHC card slot that supports up to 32GB cards, and a 1024 x 600 display that's optimized to minimize glare for reading. The lack of full app functionality through Google's Android Market is also a drawback but at $250 the Nook sounds like a pretty good deal overall.
