Seriously though: as a developer or tester, Subversion is designed to be efficient and effective for your exact use case.
Yes it is simple, but not too simple in my opinion.
And remember you can always revert.
In several years of intense use I have personally encountered
- one bug that can be worked around
- one issue that I could live with
- one feature whose attributes meant I had to modify my work flow to avoid getting tripped up
Coupled with the power of the estimable TortoiseSVN, for small to medium projects you have all the power you need at your fingertips.
Learn it and use it well...
