One for the nerds....

So I now have 2 or 3 machines I use for tinkering with the little projects I have, and I'd like to keep the code synched. There are many tools for this, of course, and I'm not wanting to start a religious war about which tool I should use, but rather seeking advice on how to use them best :)

Assume, for the sake of argument, that I have access to git and/or subversion. Assume, for the sake of argument, that I have a ~/Code directory, which has, of course, a Python directory and a Perl directory, which then contain project directories and library directories.

Assuming for the moment that I don't care so much about synching "broken" code - in that I want to be able to half-finish something on the desktop, commit it to the repo, and check it out on the laptop to keep tinkering - as much as I care about the latest version, is my best strategy to commit ~/Code en masse and then just update en masse?

Or should I commit each project individually to the repo, so I can branch later if need be?
