For me, the hardest thing about learning Git is the lurking feeling that I have to learn it because it has become an unavoidable fad, not because it is the best approach to version management for most common use-cases.
I think your attitude is completely reasonable, and I'm with you on your skepticism. However I am pleasantly surprised that, for once, a software fad lines up with what is actually technically superior. Linus knows how to design software correctly.
