Nobody cares except for the three hate mails that I'm going to get, but I'm switching from SVN to Basic TFS.
I store copies of all the source code, tracing back to when I got access to the code, that's called SCCS, SCM, and probably some other acronyms. That means that I can see exactly what changes I've made to the code over time.
SVN is a fine product, but for some reason I kept getting errors about needing to execute the cleanup command, and got frustrated by what I needed to do to fix the issues I was having. I was also having some display issues linked to using 64-bit windows.
By switching to TFS basic, I also get to add and attach bugs to specific code changes, something that isn't possible with SVN by itself, and which will help me down the road when I want to know why I did something. I know that I can get bugzilla or other products to get the same functionality, but this is also what I'm using at my day job, so it makes my life a bit easier.
