Yes. That's no secret, and it's on purpose. Jobs has talked repeatedly about how Apple's core strength is that it controls "the whole widget." The software is designed to run on the hardware, and the hardware is designed to run the software, both at the same time.

Ahh, well, you should probably do a bit of fact checking before making such sweeping statements. This is posted from my Dell 8400 running Leopard 10.5.2 (that's right - the absolute latest & great form Apple). It runs like a dream, NEVER crashes, and is as fast as lightning. Minor hacking in software to get it running, but it is AWESOME (and sitting proudly next to my Mac Pro)...

Hey... that’s pretty good
But most people can’t do that Hackentosh hacking

Your Dell 8400 is obviously an “Apple quality” computer and would run Leopard just fine without any hacks. Except that Apple has purposely crippled its OS so it runs only on a computer you buy from Apple
