I have a Kobo Touch, got it on a sale and find it very useful. I have been loading it with pdfs, rtfs, some epubs, and what ever other format it will load...it has a 16 gig micro SD card I load up from time to time. I have found the current version of the software on it handles pdfs okay for pictures, and I can enlarge the print, but not as nice as the epubs I have. rtfs read well, but miss the cover art the epubs have. I also have a project going on where I am scanning an old diary my Dad wrote during part of WWII in the navy and sharing it with other family members, an epub might be a nice way to share it.
