I used the Dell Latitude line back in 2001ish, and I'm pretty sure I had a lemon as my computer went through 11 motherboard, give or take, but one thing was for sure: Dell took care of me in a way that Apple never did. The computer was always fixed within a day or two, and it was fixed at my workplace. None of this mailing it in or driving an hour to an Apple store BS.
then I had a samsung laptop, followed by a MBP, and I'm back to a Dell.
It's a Dell Vostro V13. It's aluminum exterior, and quite classy looking. Honestly, if it didn't have Intel integrated graphics, I would like it more than my MBP... I got it refurbished off of Dell.com for under $500, and it's great. I get about 3-4 hours of battery life, it's about the size and weight of a MBA, but with more ports, so no complaints there!
comparison: I gave up OS X, a backlit keyboard, and a usable graphics card, for true Windows 7 support, an SD port, eSata/usb port, an express card slot, and about $1000. It was definitely worth it in my opinion.
