I used to work for a computer store. Back in my salad days, I worked for a place in Dallas owned by Mark Cuban. Of course, I worked for him before he got rich selling his company to Yahoo!, bought the Mavs and made a spectacle of himself on Dancing With The Stars. (I’ll admit he’s got more stones than I do on that one.) Mark sent me and several other sales reps to a seminar conducted by IBM on their then-new PS2 computers (remember those?). IBM had come out with a “desktop publishing solution” that consisted of a really cool little laser printer . . . that would only work with the slowest, most under-powered PC in their entire lineup. That’s because the slot in the PC needed for the printer hookup was an old-style slot, instead of the New! Improved! slots found on the rest of the PS2 line. I raised my hand.
