13" retina mbp with 512gig ssd and 8gig, external 30" dell monitor w/ das keyboard when working at my home desk. A variety of dev including C/C++, C# (windows in a parallels vm), Python, Node and Erlang. Typically have multiple VMs available when doing dev - mainly FreeBSD, sometime Ubuntu. My MBP is a unix machine I don't have to worry about. Things just work. With some embedded work, I do need to jigger with drivers, but I don't do a lot of those projects.
