That’s not as much of a deciding factor as you might think. Enterprise laptops are stupidly overpriced; I wouldn’t be surprised if buying Macs didn’t actually save the average corporation money.

The real cost is in the support contract, and any CIO or senior manager knows this. The trick is finding a company to provide Mac hardware support at an enterprise level. None of this going into a Genius Bar and standing around for an hour until an employee deigns to notice you; they want a telephone number they can call, get someone 24/7 (or some proximity thereof), and get someone to come over and fix the CEO’s laptop when the battery swells up. Or, more probably, when they run a diagnostic and find out it’s bad memory, or whatever - they want to be able to swap out hardware on a call, and have a rotating upgrade plan, and all that shizzle.

The cost of the laptops is almost incidental.
