What with the latest news showing this ghastly creation has blue tooth, proximity sensor, iOS update problems, battery longevity problems following successful iOS upgrades (makes it more of a resource hog) it's clear that Jobs/Apple have taken the hint. They have hidden complaints about them like so:
