OS X can be installed on a PC...but have fun with doing updates and getting all your drivers to work correctly...
and Mac's are not much more expensive...$300-500 generally...and with an operating system that I personally feel is a million times better...It's worth the extra price...and mac laptops are built way better than any cheap asus/acer/hp/dell plastic laptop...they're smaller, better battery life, and have the best keyboard/trackpad and a very good screen...but the only thing that matters is the cpu and ram, cause you don't actually use the keyboard/battery/trackpad/mouse etc...only cpu and ram...duh guise.
now...mac servers are WAY over priced...mac personal computers, not so much
