Who do you know who buys an iPhone and an iPod Touch for themselves? It's usually one or the other, so they aren't losing any sales releasing these two products at the same time. Yes, lots of people get an iPad and and and iPhone, but they don't have to buy them at the same time if they can't afford both at the same time.I think this is completely off the mark. You forget that Apple has shareholders to answer to. They need to stagger product releases throughout the year to meet sales goals for every quarter. Trust me when I say that they understand that most people can't buy all these new shiny devices at once. My guess is that we will see a new iPhone in June-July to get it back on track. The only reason it was pushed back is because the tsunami slowed production. No new nano or iPod touch next year and a refresh of the iPad and mini in October along side of the iTV or whatever they decide to call the damn thing.
I guess we'll have to wait and see if they start selling the iPads in March again and the iPhones in June just for the sake of staggering them.
