LG UltraPC (Model 13Z940) laptop
If thin and light is what you're looking for in a laptop, then you can't go past LG's 13.3in Ultra PC 13Z940. This thing tipped our scales at 971g, and even had Sony VAIO Z enthusiasts commenting on how light and mobile it feels. It's not let down in the speed department either, with LG offering this featherweight in both Core i5 and Core i7 versions. We looked at the Core i7 version for this review.
