Best of luck to the ones "affected" as everyone that I know who works at Apple are already overworked, stressed and being asked to work while on vacation.
Ditto for certain groups at Google (cough android cough).
Either have a dedicated research group, or give people a pass at being 20% less productive at their regular job.
Here's a novel idea.. increase your workforce by 20%? I know, that's just crazy talk. :)
The side benefit is that they have geniuses working there.
