My machine is beefed up so I'm sure someone else's cost using less powerful machine (Intel P3 or something...) is more than mine. Ditto with VS.NET 2010 or future version of Microsoft IDE when used in older machines.

Shall we count the cost of using plugins as well? Including OS boot time and such and such?

Sorry, what I mean to say is that I don't know what you're talking about of this "waiting on it".
