Query: A disappointment

I'm reviewing the second unit I've had. I returned the first one because of static on the display, but the second one exhibits the same problem, and other reviewers have reported it, too. Summary: Static on the screen, EXTREMELY slow performance, doesn't show AVIs at all, can't play MP3s while viewing photos. It's a barely-adequate display for JPGs. The only reason I'm not returning it (again!) is that it's fine to leave on my desk at work, and cheap enough that I don't worry about it.
