I'm impressed, You will be too when Microsoft releases the gold code version of the browser before the end of March, 2006.
Alongside new anti-phishing and anti-spyware features, the browser has an excellent tabbed user interface that works like Mozilla Firefox.
I like Firefox, although I wasn't impressed with the fact that v1.5 has been hit by the latest in a string of security flaws.
I also like IE 7.0. I don't normally praise Microsoft, but it looks like the company-that-Bill-Gates-built has at last been listening to its users and designed a browser that offers them what they want - security in an easy-to-use package.
