Remember the old Power Computing Mac clone days? The big advantage of the Mac is also what holds it back. And that is Apple's control over the core hardware and software and NEVER LETTING GO. Well they have had to open the system a little since the old days but not much. Which brings me to the first sentence the Mac clone days were a disaster and that's why they are no longer on the market.
We tested a couple of them. We also tested Job's NEXT computer too. It went no where.
