I have a Thinkpad, which is one of the most (if not the most) solidly built laptops you can get. It's black, ugly, and all business; I love it. I bring it back and forth to my classroom everyday, and even let my students use it. I would recommend it in a heartbeat, especially for business or professional use.
If you want something nice, sleek, and pleasant, the Sony should be fine; however, I've heard good things about the HP Elitebook and Envy.
