Pay more, demand more, get more. Only idiots (or the truly broke) focus on cheap when they're standing in the spotlight. What you really want is value. And given that their stock didn't crater in what is, again, the most sensitive transition imaginable, their non-asshole savvy already paid for itself several times over in the last 48 hours alone.
If you're going to cut corners, play lowball, or just or drive a hard bargain, fine. But be sure you're doing it in places where you can afford to lose he deal.
Look, I'm not an Apple investor and I haven't bought any apple products in the last couple years or so, I really don't care and it's not my business. But with my read on human nature, the guy would do the same exact job for 10 mil a year as he would for 58 mil a year.
Y'all really don't think they could've gotten him for cheaper?
