Thank you for the tips! I don't plan on using the Surface as my primary machine. It's a toy, but a fairly capable one, and thought I'd share my experience, since others seemed interested. :)

I have a desktop machine both at home and work that are more than capable machines. As well as a fairly capable laptop. While I don't have the experience with Poser, I do have experience with other 3d modeling software. 3ds max and zbrush are part of my stable of software. Though rendering can be a chore in 3ds max as well.

Again, just sharing my experience with the Surface Pro. It wouldn't be the choice of an artist, I'm sure, but I'm still impressed with what it can do. After effects, premiere and photoshop as well. Though stylus pressure sensitivity in Photoshop isn't currently working (Adobe has mentioned an update to resolve the problem).
