It's interesting to me that nobody has yet mentioned the Bloomberg terminal, which is basically what the author is describing. It seems Bloomberg "got this" a while back, and dug their heels on for their keyboard-driven terminal-like UI whilst all other shops were going w32, Excel plugins, Web, etc. It's not sexy by any means, looks like it's from the 80s in a mainframe, but it works well for a lot of people.

Images, check. Fonts, check. Command-driven, check. Lightning fast, check.

Moving traders and other front-office staff away from BBG terminals is next to impossible due to the drop in efficiency and familiarity.

Pretty much every "function" (more similar to what devs might call an "app") can be launched via a command typed into their command bar. And it's incredibly well indexed and fast to search. Everything from reading news, checking messages, seeing a quote for AUDUSD (then subsequently purchasing). No mouse required.

Edit: typos
