I just bought a T91 and I have to admit, I'm loving it more than my Sony Reader and Smartq7. I love being able to read any file format without having to worry about converting!
I tested a couple of comics using comicrack and cddisplay and it looks amazing..
Also the weight isn't an issue to me, I'm not looking for something to throw in my backpack, just a reading device to use while at home
