I haven't had any issues with my Touch that a simple restart didn't fix.
But I also haven't updated the firmware and won't until all the issues have been worked out.
Having said that, I have gone back to using my WiFi Kobo because I prefer the way it displays the books in the Library.
I can easily see what books are Finished and the % Read of any others I may have opened.
I won't be updating the Touch until Kobo re-instates those designations or provides a means to do collections. If they decide to not do either, I'll be selling my Touch.
