There's ways around the Mac client limitations, though I really wish Apple would just give us a decent power user option already. I almost wish they'd sell a "Developer Kit" which would be an apple branded mobo with an Apple bios with install media. Then you could stick any compatible intel cpu, compatible gpu, and diy it... maybe mobo + case as a barebones... even if it was $500-600 for the barebones, I and many others would still pay that much vs. hackintosh route.

Then they'd just need to release maybe 1-2 motherboards every 12-18 months. Say a full ATX and an ITX variant.
