Whatever, bro; I have some iPads and iPhones (all 8 models, actually) to go along with my Android (and various other) devices, but I certainly don't have a 'team', whether it be Wal-Mart vs Target, Apple vs Sony, or broccoli vs cauliflower.
A juror is by definition a layman in America; however, other places do in fact exist, and there are and have been all sorts of qualifications for being on juries around the world.
Finally, you are right: it was indeed the impossible logic of the damage awards that makes it possible to just say it plain that the jury in that made a fast decision that was clearly (incontrovertibly) erroneous.
(I think that other aspects of the verdict also show incorrect understanding/thinking, but that discussion gets more nuanced.)
