Hey Hey,

I guess it depends on how it operates on whether or not it's useful....

If you just want the glimmer of MacOS X You can theme XP as if it were a Mac... right down to the fancy Dock...
If you want the BSD functionality.... well that's a given... get some sort of *nix
If you want it for testing... then maybe.
However the only real advantage of Macs comes from their power with apps like Photoshop... Will the emulator have the power to allow Photoshop function at Mac type speeds... or will it run as it does on a PC (about half as fast as on a Mac).

For me... I'd rather save the $50 and download PearPC.... It's definately cheaper (Free!) and it's open source... I'm just waiting for work to OK me using one of the MacOS X licenses and then I'll be test driving the software... I've been staring at my copy for ages...

Check it out -- PearPC.

Peace,
