Web Tablet

I totally want a web tablet. Tech Crunch have a good idea of what I mean. There have been lots of rumours of Apple doing one lately.
As well as web surfing in front of the TV, this would be a great eBook reader. I currently use my Nokia n61i for the former, and would really like a cheap eBook reader.
I'll buy one for less than $300 AU.
