hg is easier to type than git. That's 33% better at least(with integer percentages, it's event better with float percentages... and even better with fractions).

Imagine typing git 20 times? Well can you see it now? Good.

NOW, imagine typing hg 20 times, that is 60 keys pressed, VS only 40 keys. You'll probably make less errors with 2 keys too.

git didn't bring anything new to version control... with it's 3 key system. svn had 3 letters, cvs even had 3 letters. However hg has brought a 33% improvement to version control -- with it's revolutionary 2 letter system.

Obviously a break through. Obviously fucking cool.
