Slowly but surely, the worldwide PC market is drying up. In the first quarter, a recent report from IDC says that worldwide PC shipments have slipped 4.4% year-over years. And not even Apple has proven immune to the wasting away of the PC market, but they’re still making up for it on other ways.

Apple has always been considered the underdog of the PC industry, although Mac sales have been on an upwards trend for the last few years while the rest of the industry continues to take a nosedive. The iPad is cannibalizing PC sales, and PC manufacturers are starting to concentrate on the smartphone and tablet space. The “PC” sales numbers are still not quite matching up with reality: the iPad is a personal computer, and Apple is crushing the competition.

With that in mind, research firm Gartner has released its PC shipments report for the first quarter of 2012. According to the report, Apple sits as the third largest PC maker in the U.S.. And the iPad? Well, no one can touch the iPad.

It’s hard living in a post-PC world, especially if you’re chip giant Intel. A Wall Street analyst downgraded the company from “Buy” to “Neutral” after key PC makers signaled plans to adopt rival ARM – not to mention the smartphones and tablets also throwing sand in Intel’s face.
