If going the PC route, I highly recommend Lenovo Thinkpads, particularly the T-series:

Not flashy, but well built and has little things like drains under the keyboard in case of spillage, and a reinforced top in case of droppage.
Also, the Thinkpads always have the best laptop keyboards on the market, bar none.
I only buy Thinkpad when I get a new laptop.
