It actually happened today and I’m sold.
Due to installing the monthly Microsoft patches, IE decided to close whenever I opened it. A few hours later I isolated which patch actually caused it, and removed it and IE came back to life.
But it was too late.
In the mean time, I switched to Firefox, installed a few extensions (especially the cool CoolIris) and GreaseMonkey. I also went to LifeHacker for some info on GreaseMonkey scripts and installed a few.
I’m staying here.
