I'm one of them as well. I'd also love to use git. The issue I have we it is that I feel like the "port" to Windows was more of a crowbar sort of operation rather than a well thought out plan to make a program cross-platform compatible.
Install TortoiseSVN. Done.
Install TortoiseHg. Oh it needs something else. What's it called? Ok. I need msysGit. I'll get that. Ok, they're all in beta? Whatever I'll just get one. What? It runs on top of Cywin? And on, and on...
Am I missing something here or is it really that convoluted? I work with non-programmers (engineering types) who program and I need it to be easy for them. Any recommendations?
