Has anyone got any experience of Tablet PC's yet?

I'm looking for something which is 3G and wi-fi enabled, which I can use on my travels. I'm not keen on net-books and decided to wait until tablets became more affordable.

I quite like the look of the new 2011 Samsung which runs on Android 3.0. They do 8.9 inch and 10.1 inch screen versions.

Any advice or alternatives? ....and No, I don't want an I-Pad.
