I have heard the "inside" price, if you work for Adobe, was $40, so get a job with Adobe? I believe it was licensed for three computers, but one died, and I put it on a "new" third computer.
;-)
Professors' price at CSU Bookstore was $200 last year, at that price, I would not worry about the upgrade.
I'm still trying to learn CS, which is straining my old computer, though I am shopping around, not very hard, for a new computer, and will wander to the bookstore to see what they have.
University has a site license for several other programs, unfortunately, not PS.
