That goddamn broadcom chip (enable powersaving on it and it degrades drastically, basically unusable, plus installing a proprietary driver is a huge pain in the ass if you're rolling your own kernels with any frequency) and the complexity of setting up EFI only boot -- you have to manually compile grub2, you need an HFS+ partition with a /EFI directory, and then you need OSX on separate media that you can boot into in order to 'bless' the partition as bootable -- are the two things keeping me from switching my MacBook to linux permanently. The reduction in battery life when switching from OSX to linux is also annoying, but you can tweak stuff enough (via powertop, etc) that it's reasonable enough.
