Several years ago I bought a Dell mini 10 for $100 that had been converted into a "hackintosh". It runs all of my Mac programs including Band in a Box. (Separate purchase of BIAB software of course)
Everything works well but the trackpad cannot compare to my Macbook. I don't think the newer Mac OS can be installed on it however and I don't want to take a chance of messing up what already works. It is a good backup for my music programs.
