Apple has sold more than 2 million iPads since the device debuted April 3, the company said Monday.
It's safe to assume that the vast majority of those sales came from the US market, as the iPad went on sale less than four days ago in Australia, Japan, Canada, the UK, Spain, France, Germany, Italy, and Switzerland. Apple didn't say how many of the 2 million iPads were sold internationally.
Speculation that Apple is having a hard time keeping up with demand for the iPad seems to have been confirmed by Apple CEO Steve Jobs in the sales figure announcement.
"We appreciate [customers'] patience, and are working hard to build enough iPads for everyone," Jobs said in the announcement.
Apple said that 5,000 applications built specifically for the iPad are now available in the App Store. In all, Apple has more than 200,000 apps in the store that are compatible with the iPad.
It took Apple 28 days to sell its first million iPads and about the same amount of time to sell its second million.
The company also noted that the iPad will be available in nine more countries in July, though it didn't specify which ones.
