Git has been "flavour of the month" for 3 years now. ;)
I'd like to actually read stories of people who willingly went back. Could you link them?
As for why SVN is hard to use, just a few points: It's a lot of hard work to separate whitespace-change commits from actual content commits if you end up having both after a hard day of hacking. Its merge logic is completely inept in dealing with complex things, for example it regards two identical changes to the same thing in different branches as a conflict when merging. It is impossible to fix something in a set of commits if you realize it after the fact, because committing means publishing; in Git you can fix history BEFORE it has become history.
Also, here's what is bad about a central repository: You have no fine access control. All you can do is give a person access to read or write and that's that. If you want to look at their changes before adding them to your body of code, you can only allow them to get the code, do their changes, and then send you an
