I've been running it without any problems. Navigating, manipulating and such works well. I'd say the worst problem is some of the buttons/controls can be difficult to tap, but when using the stylus that came with it the tablet, it's not really an issue.

Rendering takes time, of course, but I don't have much of a comparison for how long renders typically take in Poser, as I'm new to it. But, after installing Anastasia, and rendering one of the setups that is included with it (model, pose, lights, backdrop), it renders in probably ~2 minutes.

The tablet hasn't had problems with much of anything I've thrown at it. I've loaded Mass Effect 2, Bulletstorm, and a couple other games, and it runs them well. Typically at 720p, with around medium settings. Obviously not a gaming PC, but it definitely holds it's own.

If you'd like to know anything else, I'd be happy to help, as you've all been helpful to me.
