This comment is especially funny to anybody who's run QGIS

Yes, it has a better UI than ArcGIS, and uses less memory, but only slightly so. It still looks like it escaped from 1995's Neckbeard Labs, is clunky as heck, and eats tons of memory as well.

It's still a great piece of software, don't get me wrong. I wouldn't trade it for any other GIS tool. But there's a long way to go for GIS software.
