Faster is just one part of the whole experience. Buy a ssd and put that as your main drive in a mbp and you will have a faster computer and one that is aesthetically pleasing. The trackpad on the mbp makes it usable as a laptop without any peripherals. The fact that I can have my mbp sleep and wake with a reliability is one of the largest selling points to me. Every windows computer I have ever owned has consistently failed me on this point.

Edit: I guess I should make it clear that I am agreeing with you.
