Cool, great. Except that the Windows command line sucks and bash is uncomfortable to the point of unusability on Windows. I will use a shell (not bash) on Unix platforms where it is properly integrated and meshes with the rest of my workflow; this is not Windows, and attempting to attach it to Windows with baling wire does not work for me.

My experience with source control systems--you know, including ones that aren't git--is that you can generally find a good UI for them. SourceTree on Mac is great for hg and git. Tower is great for git, too. Even TortoiseHg is a country mile past TortoiseGit in usefulness.
