So all in all i have a jetBook myself and i read it on the daily like its my job
Its comfortable, small, light and readable under almost any condition. With the TFT screen opposed to the E-Ink, it's actually more visible under low light conditions and offers minimal glare.
Even though the screen is 5" the ability to regulate font sizes makes reading a lot easier than you think. Plus try stuffing a 6" screen in your blazer pocket - impossible trust me!
Even though there is no DRM support (hopefully in the future there will be) i myself wasn't looking for that and am now free to download any classics i want - which i absolutely am obsessed with anyway. There are so many books out there anyway that you'll never even read through them all!
The button layout is very ergonomic and you have the ability to find words and switch to pages instantly. Another cool addition is they have a built-in dictionary. You can actually look up definitions for words you've never seen before and since Ectaco makes translators too, they actually have a built-in device that translates those words from English to Polish, Russian, or Spanish, so you can actually learn these things in addition while you read! (pretty cool since i take Russian courses at night anyway)
As far as the contrast goes, the TFT allows for a sharper view over eInk (there is actually data out on that, ill post a link next time i come across it) so the words are really visible.
Hope i helped with this info, but you really have to try the jetBook and hold it in order to fall in love with it quick, plus i think they're selling it for $169 on newegg.com right now so that's definitely an UNBEATABLE deal
