Wow this response is chock full of irony.
Macs essentially require Windows to be installed to get full functionality out of the hardware. You need it if you want to do anything other than syncing your iDevice or playing with your pictures in iPhoto. Everything "real" requires Windows, and those things you can do in OS X aren't guaranteed to be compatible with their Windows counterparts, so you still need Windows to guarantee compatibility with real world work.
Macs certainly can't do everything people want. They can't play blu-ray movies without a lot of additional and costly hardware, even when they can play blu-ray movies they can't playback the high end audio formats. They can't play games adequately. When it comes to music, the choices for audio hardware are extremely limited. Theres no 64-bit version of Photoshop on OS X, so they're no longer the platform of choice for Photoshop users.
So going by Apple's own logic, Macs are terrible values at any price because you can't do what you want with them, and what you can do with them requires a secondary OS be installed for full functionality.
