On an individual level I just don't see the point right now. It's not that it's particularly bad, it's just that it doesn't fix anything important about 10, and there is nothing I could do on 11 that 10 won't let me. From a point of view of risk, changing is almost certainly worse, between fixing no major issues and introducing a lot of change all the same. From a group perspective, I imagine that slow adoption will put more pressure on Microsoft to fix what people are disliking about it, so politically I think not upgrading right now is better.

So that is a very mild "probably not" from me.
