No, waste of time and it lags.
Well, I don't know about anyone else here but I don't really notice, let alone need, anything they added. I don't really use those extra features, as long as I got a nice IDE and a working compiler, I'm happy.
Unless you specifically want/need to develop with .NET 4.0 there's no need to use it for anything people do around here.
Visual studio 2k10 Sucks.
Visual Studios 2010 is a crashy piece of shit
Just depends on the developer I guess.
Things I like about it
Windows Mobile Phones IDE
Shorter syntax
Auto implemented properties
I can bind vb to dynamic languages , Ruby, Python.
VS 2010 is very buggy, but in time I think it has a-lot to offer
