Asus Eee Pad Transformer TF101

The Asus Eee Pad Transformer TF101 Tablet doesn't stand on its own. But when paired with its matching keyboard dock, the Transformer morphs into a tablet that strikes an admirable balance between productivity and entertainment. At $399 for the 16GB Wi-Fi model (or $499 for the 32GB Wi-Fi model, prices as of May 6, 2011), the Transformer is the least expensive Android 3.0 tablet to date; and the smaller-capacity version bests Apple's iPad 2 by $100.
