The Asus Eee Pad Transformer is already in short supply
The Eee Pad Transformer launched today, with a prestigious lineup of retailers, and some smaller ones. And they're already in short supply. But that doesn't mean that Asus has reached Apple-esque sales figures. Asus had previously warned consumers that the Eee Pad Transformer would launch in low quantities.
Asus' tablet carries a pretty reasonable pricetag of only US$399, but that doesn't include the dock, which will be available in May. Its retailers include Amazon, Best Buy, Fry's, J&R, Sears, Target, Wal-Mart, TigerDirect, and more. As of this writing, they all seem to be out of stock. But there are some marked-up units available from resellers on Amazon if you're willing to pay.
