It appears that ASUS is finally ready to show its line of thin-and-light machines some Sandy Bridge love. Swedish site Technytt claims to have the exclusive scoop on a trio of laptops — the U31SD, U31E, and U36SD — that will find their way to retail channels in late May. The U31SD is already showing up on the ASUS site, with the option of either a Core i5 2410M or Core i3 2310M , and a choice of Intel integrated graphics or a 1GB GeForce GT 520M card. All three 13.3-inch machines will reportedly have similar specs, though the U31E will supposedly lack a discrete graphics option. The U31SD tips the scales at a perfectly portable 3.9 pounds and it’s safe to assume the U36SD will match up size-wise with the svelte U36JG, which is just 0.75-inches thick and weighs 3.5 pounds. There’s no official word from ASUS regarding price or availability but, while you wait to get your paws on one, feast your eyes on the U31SD in the gallery below.
