Ask Engadget: What's the best laptop for travel?

Vaio 505 Extreme

Reader Mike S. wants to know what the best laptop for travel is, and rather than actually take the time to answer this ourselves, we figured we'd turn this over to the collective wisdom and accumulated knowledge of the Engadget readership. Here's what he wrote:

My old Dell is on its last legs and it's time to buy a new notebook. I need something that'll be good for business travel, since I take at least two or three trips a month. It has to be light (under four pounds), have built-in WiFi, and cost somewhere in the neighborhood of two grand (the less the better!). A built-in DVD drive would be nice, but is optional.

Any Engadgeters out there think they can help a brother out with some suggestions?
