Does anyone use services like Carbonite for off-site backup? The only hesitation I can see is wondering how long the company will exist, and if they would warn customers of an impending closing.

I'll chime in and say I've used cloning to move files from an old computer to a new one with no problems, but I just did personal files, because it was from an ME machine to an XP machine. (And if Win7 is worse than Vista, XP is going to have to limp along for a while longer.)

Years ago, a professional artist gave me some advice that has kept my HD much leaner. When I finish a project, I save it to a thumb drive and delete it from the main computer. With all the incremental saves and copies of large texture files, this really does save a lot of space. Truth is, I've yet to feel the urge to revisit any old projects, but it makes deleting it a lot less stressful. ;)
