I'm glad that I stuck to git for a similar reason; it won the war. And I understand the need for simpler tools.

But to offer a point I haven't heard from anyone before: at least I feel that I am done with it, I learned this tool sufficiently and I can move on with my life. From time to time I add something to my git toolbelt. I feel if Mercurial or anything else have won, I would maybe have to learn another tool in 5 years, whatever else got popular, and another in next 5 years. But now I have everything I need in git, and always have needed. I hold some hope in it that perhaps the learning curve was worth it.
