CLI (or Linux) users when they found out not everyone uses CLI (they dislike using GUI)
No offence, but I also use SmartGit beside your ol' Git (you should tell them, GUI for Git exists). I know enough how Git works and knows how to do it in the command prompt, but my workflow would be easier when I use the GUI. It's fine for me.
Anyways, creating a branch and merging it is simple.
