How's that planned obsolescence thing working? I know several people still using first gen iPads. And even more using iPad 2s.
You can allege a problem all you want. What it comes down to is that it's not real. You may claim it, along with the couple of other people that have the miserable need to whine incessantly, but that doesn't make it widespread, nor an actual problem. You're also rambling on about a feature that is only rumored and may not ever see the light of day. But of course, that doesn't stop you from finding more reason to complain about how miserable your experience with a luxury item it.
As far as resale goes, you're spewing more falsehoods. You act as if the Air is worthless, and that's simply a lie. No one ever gets full price for a used iPad unless they're dishonest scum. Reselling for 75% of new price, which is incredibly possible for a used Air, is an excellent return on a device you've used for several months.
Since you're so miserably unhappy with the iPad Air, why not switch to another platform? I guarantee Apple won't miss you.
