I have an Archos 605 wifi. Its decent as a media player. Nice big touch screen, web browser, gps. I think its pretty good it you plan to watch a lot of movies on it.
What I don't like about it is that the touch screen isn't as responsive as it use to be. Now I really have to press pretty hard to select something. Its pretty slow loading music or music. You can't play music while you're on the internet or using the gps.
