Also GIMP.
P.S: The article is missing Blender, as it's a go-to for "ugly, messy interfaces", even though (after learning the concepts) it's highly usable.
I just love those kinds of interface. I don't think I would enjoy using them, but I love the history that sometimes go with them. Typically they're in-house apps that just get extended until they do every thing, and only an old guy named Gary knows how everything works... sort of.
The person who works with this every day knows intuitively that "pink box, bottom row, second from left" means something specific without having to read the labels.
If this UI were redesigned in the prevalent iOS 7 style with uniform design elements, abundant whitespace, very little contrast and lots of text labels in a light typeface, I think it might actually reduce usability.
I used to have an application that could tell me anything about any student a couple of decades ago. Attendance, address, any issues from tutors &c.
We are getting back to that now slowly, but with Web interfaces on screens with 9x the area and a quarter of the information on each page.
But you know what! People are different and have different preferences. And I am far from alone preferring GIMP over the Photoshop UI.
While I love PS, I've also switched to the GIMP (for work stuff, anyway) as it covers most of my use cases.
Many of the proponents of an 'old' interface, compared to some newer remake, are resisting the change in order to defend their prior investment.
