As many of you know I am pretty much 100% Mac these days. I only break out the PC when there is a game that is not available for Mac. I've been playing WoW on Mac for well over 1 year now.
Warhammer forced me to break out the PC, which sucks because having dual keyboards, monitors etc etc is just clutter. OS X Leopard has a built in feature now called Bootcamp. Since all new Macs are Intel based you can now easily install Vista, XP or Linux on your Mac and Bootcamp takes care of all the drivers, keyboard mapping (Apple = cntrl with bootcamp).
I'm installing Warhammer now and so far so good. My 24" iMac kicks my old computers ass as that box was built almost 5 years ago and still runs XP sp1
I'm curious how the benchmarks will workout but I installed Vista with zero issues. It's very odd to see Vista on my iMac but if it works out I may have found a great solution for the Mac gamers dearth issue.
