I have an acer. Acer has a big screen, almost as big as 17 inch monitor. This is very good for AC.
In the beginning I would use it the regular way, but found out if the network connection drops, we get errors in AC. Chart is not updated properly, notes get dropped like mentioned by Barbara I believe.
So I use Acer with VNC, to access my office desktop, so no chances of dropping the connection/messing up AC.

The only thing I dont like with any tablet is : I have to carry it around. I like my hands to be free. So most of the times I use desktop with wireless keyboard.
