In the current PDF firmware there is an 80% zoom option. Is this retained in the beta? I read a lot of PDF's with the jetBook and it works well. I only wish the normal page controls would turn the page as well as scroll.
Also, for both people who commented on T9, you are incorrect. The jetBook DOES have T9 support, in fact, for several languages! You can do T9 English, T9 Spanish, T9 Polish... when typing in text, you need to use the page-up/down buttons (bottom left of device) to change the mode. Try it!
