Sure, but that kind of data can be misleading. If your app works like a dog's breakfast in IE9 already (and it does), then hardly anybody using IE9 will be using it. That doesn't mean there aren't companies stuck on IE8 who would love to use Google but can't.

Or the companies that force the use of IE 8 or 9 are unlikely to be the kind of companies that want cloud apps.

I don't understand how you can be "stuck" using IE8. If you are in a position to decide to use google apps surely you are in a position to require IT to update the damned browser.

Edit: Not as clear as intended, making a company level decision on one IT choice should surely allow you influence on another.

> update the damned browser

IE8 is the latest version of IE supported on XP, so for people who don't control the OS, they are on the "latest version" already.

That's true, but I think 'Windows = users on IE' is not as much as a force as it used to be. Corporates who have SOEs are on newer versions, smaller organizations don't seem to mind (and sometimes provide) Chrome installs.

But if it works that bad on IE9, how is it going to work on IE8?
