Today I published a very beta ArtDock that I've tested successfully with Softimage 2015 on the Surface Pro 1 and 2. I probably went overboard with the keyboard shortcuts, but I think it's pretty cool to run XSI with only my fingertip and pen.
Also, the latest version of the Mudbox dock is very "handy."
If any of you have Surface Pros, I welcome your feedback. http://surfaceproartist.com/blog/2014/6 ... timage-too
