No one is going to buy a netbook in place of a tablet.
Apples and oranges. They are both fruit, although not the same, however both have their places in the fruit bowl!
You simply don't get it. I know you are an Apple Hater, but why not try a high end Android tablet or wait for RIM's Play Thing?
Personally, I love tablets/"pads". For the record, go browse BBRV's blog history, and you'll see many references (and pictures) to prototype tablets based on pretty much the same HW as this. And Android to go with that!
But anyone wanting to type anything longer than a street address, an e-mail address, or a web URL *will want* a keyboard. And just because anyone wants to type something, doesn't mean they will need the power (and noise, size and weight) of "a real computer"!
I have done some office work on my Efika MX. Worked just fine!
