It's apples to oranges (pun intended).
Apple saw that Microsoft whored it's OS to anyone who paid the fee. The fault in that model is obvious: manufacturers will pay the fee and cut corners anywhere and everywhere.
Customers will rightly scream that MS doesn't run on their machine, and MS will run around patching holes like idiots. Which is exactly what they've been doing for the last 10 years.
Apple is letting the market come to them. They've got a rock solid OS and they own the whole game-- har and software. There have been rumbles in the past about licensed hardware, but imho it's not worth the trouble.
While MS crumbles Apple will take more and more of the market until they're comfortable that they have what they need to dictate terms to vendors. Then they'll pull the trigger and MS will be a bad memory in the consumer market.
They're already the most reliable PC platform.
Watch, you're going to see anti-trust attacks on Apple within 5 years.
Some will, but it wasn't Microsoft doing it. They don't build the hardware.
If the OS is built for the hardware, hardware developers don't have a market for new technology until the OS vendor agrees to make their OS compatible. You can tell me that's not going to work to stifle hardware development, but I'm not going to believe it.
