A real POSIX shell that isn't slow. A fast gcc and the like.
It is a pain to compile psycopg2 and lxml on windows compared to linux. Cygwin and virtual machines are unfortunately too slow when you are used to working in a non-virtualized Linux environment.
I'm heavily biased though because once you are addicted to the command line, it becomes very hard to live on Windows :-(
