The MacBook Pro has a couple other advantages. For those who abhor Windows and/or love Mac OS X, it obviously wins in that department. It also has the upper-hand in that you can dual-boot Windows 7 or run Windows 7 in a virtual PC on the MacBook Pro, but you can't do the same with Mac OS X on the Dell.
I'll be honest. I have really, really been looking at the MacBooks--both the MacBook Air and the new MacBook Pro line. That ability to run both Mac OS X and Windows 7 would be valuable to me. But, on paper I just can't justify the MacBook Pro purchase. For the same money I can buy the Dell XPS laptop and a Mac Mini. If I am standing in Best Buy looking at these two laptops, I am going to take the Dell and keep the extra $700 every time.
