I've been away from my desk a lot in the past few months. For health reasons I haven't been able to sit in my office chair like I used to. I don't know what the future will hold and I would prefer to work at my desk (I have a pretty nice setup) but if I can't I want to start thinking about alternatives.

I have a small laptop but it is only really for web surfing. I'd like to pick up a tablet model with some muscle that I can use to work on Zbrush and Vue scenes "on the go".

My question: Are any of you out there using this sort of setup? I'm really looking for a machine with a sensitive enough touch-screen/stylus that I can do brushwork in Zbrush (pressure sensitivity would be nice).

I'd love to hear what some of you fellow artists out there are using!
