7095 is a stand alone controller, the 7096 is only programmable with a computer, at present the software is only compatible with Windows 2000, XP, Vista and 7. A mac version is due soon. The 7096 does more, but it is cheaper because your computer is doing most of the work. It doesn't have any knobs and very few LED's. It is basically just some memory to store the program. Once programmed it can be disconnected from the computer. If you don't like computers, get the 7095, the 7095 is mainly for technophobes and maintenance companies at this point.
