I notice a tablet seems to be a bit of a hangup here in the responses. Likely this is because of Windows OS requirement.

In my experience, if a tablet can run Windows, it'll run BiaB/RB.
A Surface would work, and I've seen it run fine on an ASUS (windows) tablet also (using external drive for generation, etc).
An iPad would probably be a much bigger challenge since Windows OS is not native.

Just mentioning; an iPad would be fine to play the 'result' (mp3 or whatever) but for running the actual app it would be more challenging to actually Run the BiaB app.

/I don't have the Mac version of BiaB to test, but just having the Windows version I would expect issues with some non-Windows tablets. My W8 tablet seems to run it OK here.
//Not sure if having the Mac version even makes a difference, since I don't have it

I do not work here, but the benefits are still awesome
