> I don't think you will find multiple OSX user accounts viable/enjoyable. OSX puts a lot of important preferences (keyboard/mouse settings for example) within the user account, so you will end up having a nightmare keeping things in sync and sane.

I've used multiple user accounts for years and I found multiple user accounts very useful when there are clear separations between projects (e.g. multiple freelance clients).

The settings you refer to are the kinds of things that belong in your dotfile repo. I can set up a new account and import all my settings in a matter of seconds this way – not a nightmare at all.

> I've lately started using project-specific instances of chrome (created with the chrome SSB script). This lets me keep lots of tabs separate and easily pause work and resume later

This is what multiple user accounts are for, except they work with all applications, not just Chrome.
