I really want the $600 dollar wi-fi only version. Anandtech did a great job reviewing it. When comparing it to the Ipad, it definitely is a lot faster and more functional for web browsing...and its not Apple
I can see this being perfect for when I'm relaxing on the couch watching TV and I don't want my hot and heavy notebook on my lap. Not so sure about carrying it around in public but I would definitely get a ton of use out of it in my home.
At first I thought this whole tablet thing was a gimmick but if the prices can go down a bit I can really see these taking off.
