AHCI? Switchable graphics?
How Windows will handle the resolution will definitely be interesting, but I'm curious if Apple is going to continue to cripple the Windows experience with terrible driver support. Currently, switchable graphics don't work in Boot Camp at all, leading to sub-par battery life in Windows 7 as compared to OSX. Apple has also disabled AHCI for Boot Camp, so Windows users get less performance out of SSDs, etc. Also, without TRIM support, drives don't last as long either.
It seems like fully supporting customers who want to use other OS's is in Apple's best interest. It opens up a whole market of people who really like Apple's hardware but who, for whatever reason, need or want to use it with another OS.
