You get this (or something like it) in the OS X version of SourceTree: a tree view of your working copy, plus the Reveal Log... context menu option. So if you were going to switch to OS X anyway, purely over the git client situation, once you've spent £1,500 on your shiny new Mac you will at least not have to spend any more on the git client. (I don't know why the Windows incarnation lacks a tree view. A Win32 treeview would be perfectly functional, and they're easy to code for. (Never having seen the SourceTree code, I can of course confidently say that this would apply here.) But if you don't mind a flat list, Reveal Log... is present and correct. So you'd be good to go already.)
