I've been using GIT for simple for my personal .NET projects for a few months now. Things I like are:

• It doesn't leave droppings everywhere. Just a single .git folder at the the top of the source tree.
• It's very very fast.
• It can automatically figure our when a file has been renamed (no messing about with SVN rename..,).
• It stays out of the way most of the time, you barely know it's there.
• I only need to know a handful of commands for basic daily usage
• I can still commit without having to have a internet/LAN connection to remote repositories.
• I can host it very cheaply on Amazon S3 via JungleDisk, on a shared internet drive with NO need for a server process/daemon running.
• I can commit locally quickly and regularly, and push changes to the remote server less frequently.
• GitHub is awesome. And they have a free package.
• It's well documented.

Now I really need to sit down and read a manual to get more from GIT, but these are all good things I'm happy with.
