It's over two years old and I'm very happy with it. My only complaint is the body flexes when I pick it up at the corners but that hasn't affected it's operation.
I wasn't looking at a Dell specifically. I bought it mainly because of it's form factor, being quite thin and that it still had a DVD drive. All other ultra thin computers didn't have a DVD drive.
I wanted something that didn't weight a ton, would slip into a sleeve in my work bag, and I needed to be able to read CDs/DVDs.
I'd by another Dell.
