Convertible or Tablet Computer Experience

[HungLikeJesus]

I'm considering buying a convertible computer (converts from a notebook to a tablet by rotating the screen and laying it on top of the keyboard).

Has anyone had experience with any of these? Did you find it useful? Do you have a recommendation?

I searched this forum and noticed reference to a tablet from a thread back in 2003, but things have progressed a bit since then (I hope).

All major manufacturers seem to make them (Dell, Gateway, Toshiba, etc.) and sell them online, but I can't find any in stores. Last night I drove all the way to Colorado Blvd and I-25 to a CompUSA. They had two of them, a Gateway and an HP, but they didn't have the stylus for either, so it wasn't all that useful (the stylus is used to write or draw on the screen). I've been to BestBuy and Circuit City, and salesmen at both said that they stopped carrying them in the stores as of last year. I really would like to try one for a few weeks to see if I really use the tablet feature, but I think that that's not possible.
