Last time I managed to find a study showing daily browser market share, I noticed that the drop for old IE versions during the weekend was significant but below 50%. So over half of those users are not corporate users.
I don't like citing numbers without a source, but I couldn't find one in 5 minutes Googling. If somebody has a link that shows fairly recent daily IE usage share, we can double check my recall.
I would also like to add that one technical solution for the "IE in enterprise" problem would be allowing parallel IE version installations. IE already allows to go into old version emulation mode, but it's not 100% faithful (I don't know the details).
If it was 100% faithful, sysadmin could simply update IE to the latest version for normal browsing (or even let it auto-update, since I'm sure no sysadmin believe that he/she can QA IE better than MS for general Internet usage), and forcing compatibility (through GPO) for Intranet sites that are broken in newer version.
But since it's not 100% faithful, the technical solution would be allowing to install an auto-updating IE in parallel to IE8, and then configure a policy to automatically switch to IE8 for Intranet sites (Chrome Enterprise does a similar thing; you can configure a GPO so that the user is automatically brought to IE when he/she browses to specific websites, e.g.: Intranet).
