My 16yr kid says it's really lame. Doesn't run flash, some vids won't run. But, he says it cool being able to surf the net. I'm sure support for flash will come soon. Give it a shot, you have nothing to lose.

i like it its very good for cheaking stuph like email and myspace with out havin to go to your comp
