I like the no-local-storage dream. But what about when you're at the airport or the hotel network is broken or on holiday in indochina, and want to do some hacking? There's probably no network, or if there is it'll be expensive, slow and unreliable. Though I struggle with git, I love it that you can easily keep a tree pulled (even if you don't actively use it), and use that when you need it.
