I haven't used an eInk device yet, so I don't know how well I'll be able to handle refresh rates, etc. But it looks faster than many of the e-book programs I used (although the old reliable eBookwise turns pages faster than the eInk devices I've seen demonstrated

).
Then again, I remember when I used to have time to make a sandwich when I was using some e-book programs on the Palm -- especially when I was opening stuff on the SD card. Heckm, when I used later versions of MobiPocket, I had time to make Beef Wellington.
Well, mine supposedly ships on the 18th, so I'll see...
