"For most people, the money would be better spent on reading and typing lessons over upgrading. I know several people with top of the line systems who type with one finger."
You are saying something very relevent.
I learned photoshop from an Iranian who ran the program without ever using a mouse. All keystrokes and he was blistering fast.
I also worked with a magazine publisher where the graphic nerd sat four feet away from me. I'd post a text file to him and he had it formated in a PDF ten seconds after I dropped it into a shared folder.
His big dream was to own a G4 because every other machine was too slow for him.
He typed so fast you couldn't hear the spaces between his key strokes.
It's a good thing my talent was writing because if production speed was part of my job description I would have been fired.
I'm not quite that fast, but I do drive my supervisor batty when she asks a 'how to' question; she's big on the mouse/menu route, I'm big on keyboard shortcuts and scripts.
She asks a question, and I execute promptly, but then spend a couple minutes trying to remember where to find the commands in the pulldown menu.
