I do wish that more laptop vendors would consider the really-thin-and-light market. There used to be all sorts of weird pocket/palm PCs available in the sub-2lb range, but I guess that phones and tablets have pretty much canibalised the market.
There are plenty of 10in Chromebooks out there, some can be setup to run Linux easily. I think some of the Acer models are below 2lbs. Other than that, there are some little 6 and 7in mini netbooks but they aren't cheap. You might as well just buy a decent phone or tablet for that price. I think the netbook phase was a means to an end where we now have very small, capable PCs in our pockets at all times.
