I'm quite intrigued by a $200 web tablet like the one proposed on CrunchGear
-- at that price I'd certainly consider it, and I know places where I'd find it useful. I'd be interested to see how text entry goes -- and perhaps if it was smart enough to support a bluetooth keyboard you'd be in really great shape for the times you wanted to pull something out and type on something besides a touch screen.
But it'd be great for a lot of reading and other similar activities. I figure it's more or less inevitable that we'll see something like it -- after all, it's basically a bigger iPod Touch in a lot of ways.
I'm sure we'll see something like this at some point.
