ARCHOS 101 XS
The ARCHOS 101 XS comes to compete with the ASUS Transformer series, but carries a much lower price point. For $400, you would get the 10.1-inch tab with a tablet dock accessory (ASUS sells the keyboard separately).
Specs won't be as surprising though, as it can be expected from an affordable tablet. A 1.5 GHz dual-core processor, 1 GB of RAM and Android 4.0 make this tablet a fair contender, though.
