Apple has announced its earnings for the first calendar quarter of 2009, and while no company is likely recession proof, Apple is certainly recession-resilient. The company posted revenue of $8.16 billion and a net quarterly profit of $1.21 billion, which is huge. Mac sales were a much better than expected 2.22 million units, and though that's down a pretty meaningless 3 percent, year over year, it's enough for 3.36 percent worldwide market share. (In the year ago quarter, the Mac accounted for just 3.26 of all PC sales worldwide.)

US market share, of course, is harder to gauge since Apple doesn't break out US numbers explicitly. Looking at IDC (1130 units) and Gartner's (1135) estimated sales figures for the US, Apple's Mac has about 7.49 percent market share in the US. That's a bit more vague of an estimate, of course, but it seems reasonable.

Either way, the Mac's in great shape, despite the economy.

More impressive, perhaps, is the iPhone. Sales of the iPhone more than doubled year over year, with Apple selling 3.79 million units (according to AT&T, 1.6 million of them in the US).

iPod sales were up an inconsequential 3 percent, suggesting that the new iPod shuffle hasn't been a fast seller. It's rare for Apple to completely replace an iPod model in the first quarter (they usually go after the full lineup each September) but it doesn't look like it made much of a difference. Maybe the next shuffle could be bigger and have a real UI.
