I have an ASUS ultrabook. 13.3" weighs a good bit under 3lbs and is extremely thin. Has an annoying bug though in that it shuts itself off at random times. But when it's working it's great.

Not sure I understand the need or desire for a touchscreen on a laptop though, even with Windows 8. Just that many more smudges and fingerprints. It's bad enough on my phone and tablet. Don't want it on my laptop too. Altho I guess this new processor is supposed to have dramtically better battery life.
