Why Doesn’t Google Build A Tablet Notebook PC?

I’m just wondering why Google isn’t in the market to build a tablet notebook PC?

With all the hype of over Apple’s Tablet, and other tablet pc’s, this is something that would seem like a perfect product for Google to launch.

The main benefit, from what I understand, of a tablet notebook is the simple / instant access to the Internet.

Turn it on – and their’s the Internet!

With Google generating 99% of it’s revenue from Google Adwords (Internet advertising) having a tablet notebook that gets people to the web fast would be a logical product for Google to have.

What do you think?  Should Google be building a tablet notebook or what?
