As someone who tries to make web sites work, Internet Explorer is the bane of my existence. Historically poor compatibility with accepted web standards, sluggish user experience, bad security… the list goes on.
That being said, damn this is an awesome commercial. The visuals, message, music. If I didn’t know any better I’d download IE 9, Bing myself, and upload all my files to Windows SkyDrive.
Good thing I know better.
