A lot of the lower-end Chromebooks are surprisingly well built. Education is a huge market for Chromebooks, so durability is important. My Acer Chromebook is mostly plastic, but there are hefty metal hinges and a metal backplate for the LCD. I've dropped it several times and it just seems to bounce. The keyboard and trackpad aren't exceptional, but are perfectly pleasant to use. The only major downside is the screen, which is a fairly dim and low-res TN panel. Still, you really can't complain for the price.
