Besides piling on with the others saying I use it a lot, I'll remind you that the old history can still be available, in a separate read-only repository, after you've moved on to a new tool. Not as convenient, but still available. Some use cases are: a) "Blame" tool, which produces a file version annotated line-by-line with who and when last changed that line, along with the commit message. "Who the f*&# did that s%$@#? Oh, it was me again..." b) Searching the history of a file by keyword. Especially useful when something was deleted, and as such no longer exists in the source code, but you can find it by searching for the commit message. (knowing you can later do this gives you more confidence to actually delete things, instead of commenting them out or leaving them there in case they become necessary again) c) "All I know about that feature is that Jenny implemented it before she left the company." Filter for Jenny's user tag. d) "All I can find about that change is this old email saying it had just been done." Look at logs around email date.
