ProBook line. The new ProBook 4310s merely carries on that tradition, but it still cuts a nice figure in the flesh. While we normally like to play it safe on color choice, we have to say that the matte lid of the crimson version (pictured) really triumphs in a sea of gloss. Our only gripes are that it's a tad bit thick and heavy -- totally standard for this tier of laptop, but annoying nonetheless -- and that the sharp, square chiclet keys aren't perfect for touch typing, and are actually a little mushy in practice. We'd also much prefer some two finger scrolling to the piddling sidescrolling on offer, but we're grumpy like that.
