I've been using a dechromed chromebook (xubuntu) as my main dev machine for two years now. I've been very pleased with it. It's light, boots in seconds, fits under my car seat, and the processor is Intel so I can compile whatever.

My main use case is "car coding" side projects; On a good day I can get an hour in before work and an hour in over lunched. I launched one mvp this way, working on a second.

You are coding while having a lunch? How does that work? So you have a full time job and you leave at 12 for one hour to have a lunch break. Do you just get a takeaway food and go sit in your car and code? I don't know how you could get any meaningful work done that way. The same with coding while going to work. Although that might be easier if you are not driving.

Which machine are you using?

Acer c720, I installed a 120gb m2 ssd. It's an older machine but works really well still. I'm on xubuntu 14.04, when I upgrade, I'll most likely go to galliumos:

What kind of projects you work on? I think I'd have some difficult coding on a machine with 2GB of RAM.
