IME Kobo hardware isn't as good as Kindle. But Kobo software is open. Kindle hardware might be better, but what's the point if it's closed and limited? I'm using a PW2 at the moment (my 'other' decided to take my Onyx Poke for a test-drive, and never came back
) I'll probably get a Kobo again sometime. Basically because I have little choice. If Kindles can be jailbreaked again ever, and they have a comfort light, I might grab one and jbreak it quick and stick on Koreader.
