Re: A solution desperately looking for a problem
Not necessarily the literacy level of any given individual. In our case, key financial software requires IE8 (not our decision, personally of the opinion that somewhere there's a bought poll who keeps forcing it through). Google are discontinuing support of IE8 in about 2 weeks for our newly acquired cloud mail and apps system. And we're not yet approved from Chrome because it's "vulnerable". So we can't roll out IE9 because of the finance apps, and we can't roll out Chrome because of a security vs implementers kefluffle. Right now it looks like it will be Firefox to the rescue, although I'm told we'll be able to roll out Chrome Real Soon Now (govt tm pending).
For as half-arsed as it is, this would be a solution that would work for us. Send the finance apps to IE8, GMail and everything else to IE9 or Firefox depending on personal preferences. Of course, it probably has a fair associated cost (even $15/station is a fair associated cost when your org has 15,000+ people and I expect it would be more than that), we couldn't afford it anyway.
