I was debated, because I really loved my 4, but after a tour at the nearest apple store I gave up and bought my iPad Air.
Absolutely happy with the purchase.
I'm waiting for a software fix for the memory leakage problem, but I still have to see my iPad crash ONCE.
The only app with problems for me is Safari, and I switched to Mercury Browser for that reason.

Bought the Ultimate Crashing Machine after giving my iPad2 to my mother-in-law. Returned the Air after multiple crashes/day, and kind of hinted I want my iPad2 back, which was met with a big frown, so now I'm screwed. I'm ok with my MBA for now. Will wait until Apple figures it out.
Yet have to see a single crash out of Safari on my Air, and I'm using it not less than 4 hours a day with any kind of applications.
iOS 7 64 bit still have to be refined, for sure, but nothing like an "ultimate Crashing Machine" here.
My iPad 4 was rock solid, but it crashed a couple of times in the last 4 months.
My Air with same apps still have to.

The non-retina iPad 2 uses less RAM than the retina. So claiming the 1 gig of RAM is enough is your guess, and is not compatible with most people's experiences, soecificaly when having their tabs refresh constantly in safari.
Also, looking for 7.1 to fix ALL the issues is setting yourself up for disappointment.
iOS 7 is a real step down for stability and performance. Hopeful it gets better with 7.1, but there will still be issues that remain, specifically when it comes to the air/rMini running at 99% RAM utilization , due to Apple's stinginess/thirst for max $$$ at user experience expense.
On iOS 7 after boot my Air has 520 Mb of free ram.
On iOS 6 after boot my iPad 4 has 580 Mb of free ram.
Hardly a huge difference.
Both are retina. Both have 1 Gb of ram.
Try again.
