That's fair; all I ever really print are documents (academic papers, lecture notes, and forms that I need to sign). The printer I mentioned is black and white, so color isn't on my radar.
I'll admit that maybe I was a bit reductive with my statement, let me amend it a bit: for a large percentage of common printing jobs, I don't think a lot of people are missing out by opting to not buy a new printer (except subscriptions).
Borderless printing, color accuracy, the ability to use high-quality photo paper come to my mind.
