Apple has a huge hit in the iPhone 3G, which is selling out worldwide. The App Store is just as big a hit. iPod sales are still up, so no cannibalization by the iPhone. And Macs are selling like hotcakes, with Apple market share shooting up, sales and profits bigger than ever before, beating expectations. And Apple has “several new products” that will be released in the next few months, including some ultra-cool new gadget that’s still hush-hush.

So how does the market react? Apple’s stock tumbles 11%, down $17 per share after hours.

Why? Because Apple said it’s current quarter might not be as good as expected. Which is what Apple says pretty much every quarter, and every time they do better than expected.

Maybe it’s just the shaky market in general making speculators nervous, but I swear that these guys are economic hypochondriacs–if they got news that their heart is in great condition, their blood pressure excellent, their respiratory and digestive systems A-OK, and the doc gives them a life expectancy of 110… but the doc mentions that they should cut down on fatty foods, just to be safe, they’d burst a blood vessel panicking.
