Just heard a podcast where several experts agreed that the iPad 3 is really all that most people need for a tablet. Any upgrade will be very expensive, and only gives you small incremental improvements. Reasons to upgrade don't include a thinner tablet, a marginally faster processor or a fingerprint scanner. Until they give us something we really want, like much longer battery life or an unbreakable screen, all the Apple marketing hype will be only preaching to the faithful, who are a shrinking club.
