After using a laptop for so long, I decided to try a tablet for tuning. so far, I love it, but I did have to add a keyboard and a touchpad, since using just the touchscreen to do things like manually smoothing a VE table was almost impossible.
Other than that, I am really liking it! The 16 or so hours of battery life is amazing too.
And I know people will want to know....
Its a Dell Latitude 10, with full Windows 8.1 Pro. You cannot use HP Tuners on Windows 8 RT.
