Nice light machines are nice
"Writing this using an Acer Cloudbook which uses an Intel N3060 -- no fan at all, passive cooling -- no user maintainable parts at all in the box. Cheap, cool (pun intended!), recommended for anyone wanting a cheap, light, portable laptop."
I can second that. I had a Acer Chromebook 13 with Tegra K1 (quad core 2.2ghz arm (and a fifth 1ghs low power core), and roughly GTX670 GPU ), got Ubuntu onto an SDCard, even got the nvidia driver going including CUDA. 18 hour battery life.
There's something to be said about a sub-10W TDP setup (the N3060 is 6W TDP), no fan needed, just a little heat spreader. The chromebook would maybe heat up 4 or 5 degrees if I had it running all 4 cores at full load. Nice and light, and either a light battery with decent battery life, or "normal" sized battery adding a little weight but ridiculous battery life.
