Greg, I have no regrets. Terry (tcassidy), and also at least one other person here at the forum, have the same HP tx2000. If there was one thing I wish I could improve on the tablet PC, it would be the brightness of the screen. But for $1,000 I can't complain. I would have to pay $3,000 for a 12" convertible laptop/tablet with a sunlight-readable screen. I don't think I would be willing (or able) to pay three times as much just to get (much) better screen.
I'm happy with it. I use it daily at least 12 hours a day, on the road and at home. Garmin Mobile PC looks gorgeous on it.
