I think that's a poor excuse for not having a linux version. By that logic, we wouldn't have sublime because vim/emacs should be enough.
As I see it, the main reason I like to use linux on my development boxes is flexibility(or call it freedom if you want, I don't like doing so). I can do things in whatever way works best for me and I can create scripts/install packages to glue stuff together fairly easily to adapt to my workflow.
Exactly, I feel the same. By default, git commit just shows me "M /src/foo/whatever", I prefer to use a GUI where I can then click on that and it shows me a nice fullscreen visual diff with colour highlighting etc. Just works a lot better for me in being productive and reviewing things before I commit(an essential part of any workflow)
I use http://rabbitvcs.org/ (it's a nautilus plugin, so basically it's got the TortoiseSVN style context menu interface), and find it great. Having said that, my main work is with SVN, only use git for interacting with open source projects I need to submit PRs to etc.
