This has been pretty much exactly my experience as well.
I tried it out and didn't get hooked. Then I went to use a bunch other other similar pieces of software, and eventually came back to kick the tires again. I was pretty much 100% hooked at that point. I've been using it for almost everything for two months now. We use it on my team, and I use it for almost all my personal stuff.
I think I've gotten about fifteen or twenty people I know to use it. They really dig it as well. I feel like it's one of those pieces of software that really "gets out of your way" so to speak
