I suppose this is a hybrid of a software/hardware question, but this seems like the most appropriate place. Are the Wacom digitizers in tablet computers capable of using this feature: The 3D Brush Preview - Photoshop CS5: Painting with the Mixer Brush from lynda.com - YouTube ? It doesn't work by default on my HP 2730p. I'm assuming it's a hardware difference from Wacom's Intuos products or possibly that I don't meet the GPU requirements, but I thought I'd ask in case it's a driver issue or something. Edit: I see that some Wacom pens advertise barrel rotation. If the default pens don't, are there any tablet PC pens that have this feature?
