Considering that gizmondo isn't available until 2nd quarter 2006, you shouldn't even think about that.

Also, if you are considering that as a web tablet, note the resolution of gizmondo widescreen at 480x270, which is roughly a quarter the resolution of nokia 770. Also, nokia has touch screen input, which is not present in giz.
