Of course it's not a backup solution. That's what timemachine, superduper, mozy are for. Let's pretend that you are a graphic artist and you have a psd file with a picture for your website. You make a change that does not work well and your undo history is past it's limit. Instead of having to copy the file, rename it, make changes, and clutter up the folder you have one file with a history and commit messages that tell you what you changed. A commit message of "made the background transparent" followed by another commit "changed the font color to orange" is a lot better to see than a file name of "project_trans_back_orange_v1.psd" To each their own though. A version control system is such that it can handle versions of the project and not just versions of the source code. FWIW: I keep whatever files in the project I have uncompressed in git and it hasn't killed my HD space yet.

That would be the ideal situation.

  That would be amazingly powerful. I remember reading something about how convoluted the psd format is because of the backwards compatibility along side new features so I don't know how easy that would be for psd's.

    On the plus side, the convoluted backwards compatible nature of PSD files makes it trivial to get useful bitmap data out of any PSD.
