I'm a huge fan of Git and I think it improves my coding life drastically. But I completely agree with you that git is not better for every task. You either need a shell (which many modern coding tasks simply don't require at all) or you need a reasonably abstract GUI tool (I only know the GitHub GUI tool to fulfill that requirement, all IDE integration I know off sucks). But even in the case of well designed GUI tools you often do things like "create a feature", "send pull request to main repo", etc. If there is git underneath or any other version aware data storage doesn't really matter. A couchDB might have been a fine choice as well. So the only real use case is when you work in shells anyway and when you require the more complex git capabilities. Therefore I don't think it should be the major, hip tool everybody uses and I hope the world soon realizes this and creates tools for every day usage with an every day amount of power under the hood that can be handled without a mastery in git foo. (After having said that, I want to remind the reader that I myself love, need, want and use git with nearly everything it has to offer, but I had the time, energy and interest to dig deep into it for a long time)
