I found a model of the Acer C720 with 4GB RAM and it's been my only computer for the last 5 months. The 32GB SSD is not great, but xubuntu + all my dev environment still leaves 40% free. Browsing is fine, never had performance problems when editing either. It runs Clojure on the JVM without issues, but I've never tried/needed to run a full blown IDE. That said, it happily runs Minecraft on medium settings. There are still a few hiccups with hibernation. Using a tiling WM meant I needed to remap all of the chrome keys to get stuff like brightness and volume working. I got it refurbished for £120 (~$170) before I set off backpacking in Asia and it's been the perfect laptop. Lightweight and decent battery life. I do a lot of vector drawing and the trackpad fidelity isn't great, but that's hardly something you can ask for on such a cheap little machine.
