@mike my Chromebook is by far the best lightweight laptop I have ever bought. Caveat to that being "lightweight". For booting up and going online/checking mail, there is no better device.
However, I'm not sure how pleased I would be if they muddied the water with touch support. It frustrates the shit out of me - a user engages completely differently with K&M than touchscreen. I wish manufacturers would stop chasing the convergence pipe-dream. It's always gonna be a compromise somehow.
