I just clicked again on a small project just to see the load time. I'm not bullsh*ting but it was up and ready in ~3 seconds.Quadcore 2.5Ghz on some 3 years old Asus MB with 4Gb RAM and a brand new SSD (Crucial m4 i can recommend).
Alright fine I believe you. I can't pinpoint why I have such an issue with VS. I mean, I don't have much use for it since I'm a(n) RoR developer, but I don't really know why I hate it so much. Freshman year of high school I took my first CS class in Visual Basic and I really liked it. I said "I" 9 times. Sorry.
Some other tips here.
Like everyone else replying, Visual Studio 2010 launches in under 10 seconds for me; Visual Studio 2012 RC even faster.
