VS 2010 is the last one I got for personal use. Not enamored with the changes in VS 2012, Windows 8.* nor the cyclical abandonment of APIs. Add in the increased license cost we face on all Microsoft products at work and any announcement from Redmond gets a "meh" from me.
VS 2013 adds fix-and-continue to x64 builds. That right there is enough for me.
Beyond that, though, I'd encourage you to at least look at VS 2012, get past the superficial changes, and look underneath. There were a lot of performance improvements in the GUI rendering that added up, and there were a lot of tweaks to project search and management that became indispensable to me shortly after launch.
