I am interested in getting a smaller, more portable tablet (4-5"). Is there actually a major functionality difference between the Galaxy Tab "tablets" and the Galaxy Player "media players" or is Samsung arbitrarily designating 7" and greater as a tablet and 5" and smaller as a media player? If the Galaxy Players are severly limited in some way, are there other suggetions in this area? I was looking at the Archos 43 for a while, but the Samsungs looks like they have a lot more functionality for not too much more money. Plus Tabs get pretty good reviews overall, so if they're based on the same designs, they seem like a very good option. Any information or suggestions would be greatly appreciated.
