Most companies do. IE & Safari come with their respective OS, and if you're a Windows shop you're probably going to also install either Chrome or FF. We had been standardized on FF until they expedited their release cycle, which made keeping current too much work (this will change once it updates silently without breaking add-ons), but since we were a Google Apps shop anyway, this doubled our resolve to switch to Chrome. We kept FF around as a fallback in case we ran into situations where Chrome didn't work (Juniper SSLVPN meetings in Windows, for example). We actively try to prevent users from accessing IE (removed shortcuts from desktop & Start menu, etc), btw, except for the couple hundred users who actually need it to run legacy apps we have no control over. Note: about 80% of our employees with computers don't have internet access at all, with the exception of a proxy rule that allows them to access Google Apps (and a few other select SAAS apps). You can imagine this complicates things a wee bit.
