The Visual Studio IDE has gotten much much worse.

I started with Visual Studio 6 (mostly using Visual C++, and VB6) and it was a speedy. Visual Studio 2003 was a little slower but not bad, 2005-2008 about the same. It was all bearable and acceptable.

Now Visual Studio 2010 is painful and awful. I've got a Core 2 Duo, 4 GB of RAM and the interface is slow, you can see the GUI repaint sometimes. Clicking on the interface causes frequent pauses that take close to 1 second to respond.
