RE: Do you have any tablet?
I have an Asus Transformer, which I can heartily recommend.
I wouldn't buy just a tablet, I couldn't justify the cost for the amount I would use it (not a lot), but I was looking for a replacement laptop, and the Transformer fit the bill.
Massive battery life (14 hours on my old 101, 18 hours on my missus' new model), decent keyboard and, with a bit of experimentation, all the functionality of my old windows machine.
Plus the screen detaches as a pad when I need that.
