Thanks for the reply's. I have the Kobo app on my tablet but I never got around to using it. Right off the bat you have to create a new account before you can even test it out. And I don't intend to buy from the Kobo store so I didn't even bother with it; and I believe it only takes epubs.
I have a huge collection of .prc and .pdb books. Right now I'm using the Kindle app and Aldiko. I prefer the Aldiko a little more but again it takes epubs and Kindle can read my old .prc books. I guess I am a little too picky.
I would still be using my Axim if not for it getting wet and the battery dieing. Then I almost went for the Kindle but since I was going to upgrade to a modern device I figured it should be able to do more than ebooks. But in the end, I pretty much only read on the thing anyway.
