This is the first version of Internet Explorer since version 7 that is actually somewhat usable. They have fixed some of the worst visual crapness.

However, Microsoft remains Microsoft.

I had to manually uninstall Internet Explorer Beta 1. Then restart. Then install Internet Explorer Beta 2. Then restart. To get it working.

And this edition has a long list of things that are incompatible. In fact, I read that even Windows Live Mail is incompatible with IE Beta 2.

This is pretty incredible stuff.
