I switched to using Ubuntu for all my web development work about a year ago. I even ran Ubuntu on a £200 desktop with 8GB RAM until I upgraded to Win 8. But all my work is done in a VM using Virtual Box. I switch between two desktops and a laptop regularly and run multiple VMs. I don't waste time reinstalling my base OS, I just import my VM image and get working. My 2008 MacBook Pro is struggling a little, but not just with the VM and it's limited to 4GB RAM. Having at least 8GB RAM makes it all work much, much better. I get the joy of Linux, Windows and OSX with surprisingly very little headache. And I use Git to synchronise all my work.
