Well, Numberz... you have to remember that most of the guys posting here don't have a Mac with OSX or Tiger, so they don't know what they're talking about. But that has never stopped this crowd - they'll gladly give you their opinion about books they've never read or movies they've never seen, too.
HTC chose to use DirectX for video and not porting to Mac is understandable, based on that choice.
Sure, Apple has gotten a little behind in processor speed; that's why they are moving to Intel chips. The notebooks will be first to move. All indications so far are that you will be able to dual install Windows on an Intel-based Mac. But, you won't be able to install a Mac OS on a Windows machine.
I don't think you're going to be happy with any PC emulators. You might be better off putting that money into either a PC, or an Intel-based Mac next year. Aces High runs great even on Win98SE.
And just so you know, I'm a satisified, paying customer with a PC just for this game. There isn't anything I can't do better and easier with my Mac and Tiger OS. Good luck with whichever path you decide to take.
