How did you even checked in a 40 MB without noticing. There is at least 2 safe guards... (Git status and Git commit)

Git would allow you to roll that back even when pushed to a remote.
Mercurial would not, you would be left to the remote host providing some method of removing commits (which bitbucket does, but only via a webinterface).

I've been using SmartGit for my windows machines, as I'm not a very experienced with Git or command line repository stuff in general (my workplace uses MKS, which is all GUI), it seems to work fairly well and is pretty intuitive UI (though, as I said, I'm a beginner with git and it may not provide more advanced functionality). It's also got github integration which is nice :)

Re: Git or SVN in WRWB
 

We use git + ucpp on linux. I'm working on getting a nicer makefile generator that handles dependencies better and a native (not through wine) compiler for next year. So far, git has worked extremely well. Github is also awesome - probably the biggest plus for git.

I haven't use hg though, so I can't comment on which is better.

Why would you be checking in a big movie? You have to git add it explicitly before it will be tracked, even if you always just git commit -a. Unless you're doing git add * - but in that case, maybe you deserve the extra work ;) At least do git add *.h *.cpp if you're lazy.

I love Git's commandline interface
