Microsoft's IE in the early-mid 00's was the best, they were leading the W3C in features. Even Firefox with all the hype and MS hate couldn't take away IE's 95% market share.
Chrome has really changed everything, it's faster, more functional, and rarely ever fails. I'm also a big fan of Opera too, but for me Chrome performs faster.
Microsoft needs to understand that we are not haters and trolls, we just want to use what performs best for our usage. For many it's not IE, Chrome currently has more then 50% of the browser market and that is what Microsoft is attacking in this ad.
Microsoft has created the situation they are in and attacking their internet user base doesn't seem very smart to me.
