The reason why Mac users get so excited is hardware isn't updated as frequently as PC hardware is.  PC hardware upgrades itself 2-3 times a year versus Mac's which upgrade once a year.  Sure, you can get a fast processor for your Mac today, but it'll be the fastest (pretty much) for a year.
Buy a fast CPU for your PC today, and it won't be all that fast come another 2-3 months.  Macs are different than PCs in many ways and do most things just fine, but because hardware selection is limited, I'm not going to buy one.
On the other hand, I do like the notebooks 

  They look good, but are too expensive.  My PC I can take looking ugly, but if tote a notebook around for 2-3 years, I want it to look good.  I probably wouldn't buy a Mac notebook anyhow, I'd rather have another PC at home, just to make life easy.
