I would say the S7 if resistive touch screen doesnt bother you. For me the size is a big win for the S7 the word Portable is taken away and sitting on the train with a big machine is a bit silly looking . but Ainyul has a great point good dev community for archos is great but thats because there no help from the Archos them selfs but i can see a good community starting for the S7 aswell
You can check out the s7 in a local bestbuy store, I have tried itbefore and did not like it. It was fast with market on it. The screen was not resposive and no 3D games.
101 is nice, I was thinking to get one but I ended up getting the viewsonic gtablet instead. After flashing a custom Rom, this tablet rocks, I got 2400 score of a quadrant test. Like someone mentioned in this forum, this tablet does not work well out of the box.
