I'm one of the 'stupid' people who runs Windows exclusively on a Mac.
"Now Cathy, why would you do such a stupid thing like that? PCs are so much cheaper than Macs"
Not that much for notebooks in Singapore. Other notebooks with similar specifics were only cheaper by about US$100 - 300. However, these models were all either huge and bulky, heavy, or of inferior build quality (or just plain ugly). I figured it'd be worth the extra money to buy a solid notebook that's slim, light and plain sexy. <3
"But you forgot to add in the price of Windows."
School provides Windows XP Professional and Windows Vista Business for free.
"So, why don't you want to use OS X since you have it?"
I don't mind using OS X. It's just that for all the programs that I need/use, it's either not available on OS X, or Windows does it just as well as OS X does. If this is the case, it makes more sense to just stick to Windows.
Gaming? Windows definitely.
Visual Studio? Doesn't work with OS X.
Maya? More or less the same on both.
Photoshop? OS X does it better, but I'm not at that level where it makes a difference.
Microsoft Office? Still better on Windows.
iTunes? Is there any difference?
Movies? Same as above.
Comics? Same as above.
Web Surfing? Same as above.
Arguably, the only thing I need which OS X does better than Windows for me is multitouch gestures. However this isn't enough to make me stick to OS X. Besides, none of the PC notebooks have multitouch gestures anyway
"But Windows is so slow, keeps crashing, and is so vulnerable to viruses!"
Yeaaa, to anyone who actually does say this, you should try using XP under my MBP first. It's every bit as snappy as OS X, extremely stable (<1 crash per month), and has not been infected by a single virus so far.
I'm not that "stupid" though since I still have OS X around, should it become more advantageous for me to use it. I'm not saying whether OS X or Windows is better, it's just that Windows suits my needs better.
Hope this answers the OP's question pretty clearly.
