On the consumer side, IE is great(ish) with low power usage, good font rendering, tie-in with other MS services, native features, etc.
For developers, um no, I can attest to absolutely detesting IE in every way. Its web dev tools are slow and clunky, they are getting beat over the head in features by Chrome, Firefox and even Safari, IE11 just got prefetch and pre rendering, something the other browsers have had for years; IE looks like it will always be playing catch up. Good thing they put an auto updater in their browser, but has there been any significant upgrades to IE's feature set in the past year (implementing features over a time other than every year is important as well)?
The worst part is that Microsoft always gives the previous version a reason to exist and be a pain. With Google and Firefox, the auto updater takes care of itself. With IE11, it has just gotten an auto updater and there's no telling if Microsoft will pull an IE10/Windows 8 and stop updating IE for Windows 8.1. Already I can envision in a year or two at work we'll have to support IE10 at the least, even though it should be dead. The fact that Microsoft skipped Windows 8 (which you cannot upgrade Windows 8.1 if you have the Enterprise or education edition) really burned me. At least Apple always updates its browser one version back if you don't decide to upgrade OS X.
