Dave,
I have a Touchsmart 600 (23 inch All in One) that I purchased a couple of months ago to replace my home desk top. I keep my AC Version 5 on it and it works fine. This unit is touchscreen, but I do not use that feature with AC.
I love the computer and will consider repacing my laptop clients in the office with these when the time comes. It comes with a wireless mouse and keyboard. I do not know how easy it would be to mount to a wall. It cost around $1,100.
