I can tell you quite a bit about the Sahara Slate, and it works just fine with Dragon 9.5. You can visit the blog and go to the tablet area and find all kinds of stuff, and I have done a couple You Tube videos as well, using dictation in a not so good area, and it was working pretty well with the dual array microphones, in other words, no headset required.
