Use Mac or Windows so you can use productivity tools needed (Microsoft Office, Adobe products, if needed) and then run virtual machines for development. My 11" MBA runs great. I've only installed a few things - I do NOT install server tools (where "tool" == apache, nginx, pip, memcached etc etc etc etc). Mac laptops are still good quality, and you're NOT stuck using the Mac OS for everything, especially development.
