Emulators suck.
btw, Rich, which Mac have you bought?
True. I still think Microsoft cripples their software on Macs to try and short Apple. I suspect if I were actually running an NTFS partition on an intel-based mac it would be fine.
This is actually my lab's 15" PowerBook, purchased about a year ago. It was the iteration of PowerBooks when Apple first released the gyro to lock the hard-drive on laptop shifting as well as the dual-finger scroll feature for the laptop scroll-pad. Despite it being a year old, it still ran considerably faster than my 2.8Ghz P4-based Toshiba.
Unfortunately, my wife sold it dirt cheap to some friends who specifically needed a laptop, thinking I had the work computer to use instead. I don't know if she completely comprehends the PC/Mac differences or not... so for the time being I'm not able to actively develop XP skins.
