I somewhat liked my Kobo except for how much Rakuten kept getting more aggressive with forcing their environment on me. And then my Kobo decided to wipe and reset itself on its own, losing all of my bookmarks and other data.
Nice hardware concept, completely unacceptable software.
You should check out KOReader [1], an OSS alternative interface software for ereaders. I have it installed on my kobo and I couldn't be happier with it.
