Kno e-reader tablets

The Kno Ebook Reader due out soon is designed to work well with e-textbooks from publishers like McGraw-Hill, Pearson, and Wiley. So... students will be expected to purchase an expensive tablet AND the expensive online textbooks? (Perhaps not: Seems that it will load PDFs as well.) The features including support for notetaking with both stylus and keyboard, backup to the cloud, ability to highlight and add notes - on a 14 inch screen. It sounds...expensive. No mention of ADA compliance though they must have thought of that. Can it read to you? (Can I IM my friends and facebook and load up on music files?) Weight: About 5.5 pounds - which is a pound heavier than my quite old, but still functioning HP tablet pc. Well, the plethora of tablets coming out in the next few months is just mind-boggling!
