We like the Toshiba z830, but there are several similar models from which to choose! Either way, they’re lighter than air, packed with powerful new processing power to spare. The build quality seems great — and it’s the kind of thing you don’t mind carrying from an office to the conference room or on the flight or across town. In the USA, Best Buy has units starting at $800! Think Mac Book Air but running Windows.
One of the notebooks that has been blazing the trail is the Sony Z series, which are typically rated very highly by tech reviews. I got one on sale at a Microsoft store 18 months ago, and it has hands-down been the best computer I’ve ever owned – fast boot times, excellent performance, great graphics, business-class build quality, and, as you’ve pointed out, very light. The only downside I’ve found is storage capacity since most/all of these notebooks use SSD drives. If you plan on storing lots of photos, videos, and/or music, you may want to look at something that has a traditional drive in it.
