Albeit I have spat my guts out stating my experience so far, I must once again comment. I 100% second the observations from the part of Bluesdealer, for both the AppStore and the PodcastApp... well it seems that we kind of overlooked the issues there... and apart from whatever crashes etc there is indeed a distinctive lag in many cases.
Bluesdealer had every reason to be pessimistic, not because there are signs of mismatch, but because Apple does not react to the manifestation of our frustration.
Sorry Tim, Sir, but frankly I do not see the purpose of your apology for the drawbacks of the Maps App, as long as the iOS6 adaptation to our multitude of former devices is so poor. No reasonable individual would deny the probability of errors when it comes to high tech evolution, but we are counting more than half a month as of the update and there the "radio silence" from your labs is disappointing. It is not a matter of our word against yours, Apple. Neither is it the attitude of spoiled "fan boys". It is just that we are pretty sure and aware of the way our precious devices react "post mortem" (!) and the fact that you insist on ignoring our standard yet indisputable awareness, is insulting to us. Apple, please BEHAVE!
