Over the weekend I had a terrible experience with the external hard drive I use.  The drive completely crapped out leaving me no options other than banging it on my head.  This drive held everything in my day to day work at Magenic, so a lot of content.  And I know, the irony of the data guy being burned by not having a recent backup is truly fabulous.  Fortunately, I started using Live Mesh several months ago and had all project folders from Visual Studio and SSMS pointed there.  As painful as it was to lose several weeks worth of client documents and some presentation slide decks the code survives.  At the end of the day that makes Live Mesh my favorite Microsoft product and I would strongly recommend it to anyone that cares about keeping code or other content.
