From Apple’s press page:

By early last year, Apple’s cash balance had built to a point beyond what we needed to run our business and maintain flexibility to take advantage of strategic opportunities, so we announced a plan to return $45 billion to shareholders over three years. As of next week we will have executed $10 billion of that plan.
Hear that, Michael Dell?
They did it.
Well, half of it anyway.
Update: Mister Dell, don’t count on the other half of your advice coming true. The whole part about “shutting down” and such.
