I do use Premiere Pro, although any NLE with a decent chromakey can handle it. When I did it, the biggest limitation was that I had to keep the tablet motionless, and then shoot the screen at the same angle, without the lights, zoomed in. I got a nice effect–the lights didn't wash out the screen, and there wass no light glare. The big drawback is that I wasn't able to show any interaction by the user.
