Macbook Air 13", two 24" external displays (one is via a USB display adapter). I have VirtualBox set up with an image of Windows XP for IE testing. Other than that, I run all my webdev projects on my MBA, rather than in a Linux VM in VirtualBox. Homebrew is wicked. I use PyCharm for my dev environment (I'm largely a Django dev at the moment). Say what you will about IDEs vs text editors (but please don't in this thread, really!), it's a great tool - worth it. I have Linode VPSes running for staging/testing purposes that mirror production systems.
