I'm waiting for something with a reasonably decent screen, a decent flash drive, a few buttons. No subscription services, no wireless, no connectivity at all, no note taking or annotation features, no voice or recording... Just a thumbdrive hooked to a screen. That hardware should be WELL under $100. The extra features turn me off more than incentivize me. Currently, I'm using my DS, and it's adequate. It can scroll text, html, and pdf. Good return on a $7 cartridge, since I already had a DS.
Instead of buying this crap, you could just buy a netbook for $299.
