If you hate the portability of tablets but love the glare, you might be interested in this "digital textbook" from Kno. Weighing it at 2.5kg, its two 14.1-inch displays look like they were brought down from the mount. Kno, seriously:
If you think it looks big in the pic above, check out this hands-on shot Engadget grabbed at D8:
The specs on Kno actually don't sound all that bad: Tegra 2 running the show, 16GB storage, 6-8 hours of battery life, stylus and touch support. Of course, you're also dealing with an apparently buggy Linux UI and an asking price of around $US1000 (which, hey, $US500 per screen!).
The argument for: textbooks are crazy expensive, so in the long run this could save you money. The argument against: you could put a textbook on a single tablet (almost) just as easily. Still, it's always great to see innovation - even of the impractical variety. [Engadget]
