Mobile Dilemma

I solved the issue of constant connectivity to my inbox a few months back after much searching and testing by getting a blackberry. Now I am at it again for testing.

What am I looking for? I find the need to have a mobile system with a decent amount of power not for production work, but for everything else. I am looking at some of the new tablet PC's but need to get a few different models for testing. I am concerned because I need to do a small bit of web development and demos for AutoCad/ADT and maybe VIZ/Max. Not to mention wi-fi connectivity.

Any good products you have used for under $1,900 that you care to share?

Happy Rendering...
