The only thing that keeps me on a Mac is familiarity, and air macs are silent. I am open to any suggestions for Linux laptops that are quiet or almost silent, most have fans that rev up, I'll gladly sacrifice some CPU for quiet or even a quiet mode (easy switch on/off). Nothing I've seen matches the silence. I'm more than happy to hear anything that proves me wrong. I would be glad to hear about something like that, obviously it has to have plus like either cheaper/replaceable ram. Furthermore, I mostly use my Mac air as a remote terminal to web based services and my Linux server that I use for compiling bigger projects and home/self-hosting.
