I just went through this exercise with my college bound son. He is attending the University of Colorado at Boulder. They have on campus support for Apple and Dell products. (Meaning, for any Apple or Dell PC/Laptop under warranty, you can take the system to their repair depot and they will fix it.) Additionally, we asked at orientation if there was a preference and were told that they only required a fairly recent version of Microsoft Office products, but individual colleges within the university might have additional requirements. So, my son and I started our own "laptop hunt", with the exception that I was going to be the one to pay for it. He was looking for portability, battery life and ease of use. From conversations with others, larger laptops (16-17") were difficult to use for note taking because of limited "desk" space in most classrooms. So, we were focused on 13-15" laptops. Also, he has been a PC gamer (WoW) for a few years, but really wants to kick the habit, so gaming was NOT a priority.
We went to Best Buy to play with the various Apple and Dell models on display. The comment on the Dell systems was ... wow, they are big and heavy (Studio 15). He played with the 13" uMBP and liked the size and battery life. So, we decided that a 13" would be the best fit. We went home and tried to configure a Dell M1330 with similar features to the 13" uMBP, but the price ended up being around the same as the Apple laptop and the extra life battery was going to stick out like a wart. Additionally, Dell was going to be unable to deliver the M1330 until mid-august ... Apple could deliver in 5-7 business days. I pointed out to him that I needed, we could configure the Apple to boot either Mac OS X or Windows XP via boot camp.
Final decision: Apple 13" MacBook Pro.
