I've owned a Kobo since day one and nothing has really improved. The store is still a joke, you can only add things to your wishlist that Kobo recommends to you. Every single search results in a few things you were looking for and a ton of strange self published vanity books that don't have anything to do with what you're looking for:
Even if I've finished a book it will return to an open status after connecting to a PC.
The eReader doesn't tell the app/cloud what page you're on, but the mobile reader does.
etc etc etc
I think Kobo cheaped out with outsourced programmers and put the big money into guerrilla marketing, which is why this board is nothing but an echo chamber of marketing shills trying to outdo each other in drowning out people who have problems, I bet these guys drive their Porsches home from the ad agency every night and fire up a Kindle or Sony or something to read the latest hip viral marketing books.
