I've had a z22 for about two months and have read about 1500 print-size pages on it. In fact, reading ebooks has become one of my favorite uses for the z22. I, too, thought the screen would be too small or low quality, but not so. Its size is perfect for slipping into your pocket so you can have it w/you all the time and the super-long battery life just can't be matched. My girlfriend has a Tungsten e2 and its battery life is abysmal by comparison -- probably b/c of the larger, high-res screen. In short, I highly recommend the z22 as an ereader.
