The new iPad has the usual problem unique to Apple products, which is that they’re just too popular. According to a report from Computerworld, Apple has sold out of iPads in every country where it made the device available.

Katie Lewis, associate analyst at Yankee Group, says that while disappointing to consumers, news of a pre-sale sellout isn’t that surprising. The popularity of tablets, mainly iPads, will continue to grow.

“Apple just upped the ante with the unveiling of this even more functional iPad, which is faster than its predecessor, boasts a higher resolution screen and impressive new iPhoto app,” Lewis wrote in a post yesterday.  

Lewis says that as the gap in functionality between laptops and tablets narrows, consumers will find it easier to justify adding an iPad to their assemblage of devices.

Yankee Group’s 2011 U.S. Consumer Survey from December reveals that current tablet owners are twice as likely to purchase their second, third or fourth tablet in the next six months than are people who don’t have one at all.

“This means early adopters of the new iPad are likely upgrading from an older generation iPad or inexpensive tablet to enjoy the greater computing power the new iPad promises to deliver,” Lewis says. “Unfortunately, many of these tablet pioneers will be waiting a while longer than they thought.”

Computerworld reports that only those who placed their order very early in the pre-sale process will receive their device as scheduled on March 16. Those who waited to place their orders in the U.S. will receive their new iPads on March 19.
