This may seem a little localised, but as of today (2011-06-01) what services require the client workstation to be running Internet Explorer 2009?
I'm trying to decide if I should allow a metric-butt-load of workstations to be upgraded to IE 9 or if I can hold them back at IE7 or IE8 for a while.
I've got an old ActiveX application that has problems on IE9, and I'm trying to decide if I need to upgrade/re-write it now, or whether I can hold off until it's replacement is ready (a couple years away at least).
