Tech giant Apple (NASDAQ:AAPL) dominated technology headlines yesterday when it unveiled the latest updates to its popular iPad line of tablets.

Of course, with the rumor mill abuzz for weeks dissecting every possible upgrade for its two iPads, many of the changes were predicted well in advance. Convergence was one of the primary themes of this round of iPad upgrades. As was widely expected, the larger 9.7-inch iPad got the iPad Mini's bezel, and the iPad Mini received the same Retina display as the larger iPad.

Now, as attention shifts away from the products themselves and towards how many iPads Apple will sell, we're seeing mounting discussion of possible problems for the latest iPad Mini. According to some sources, Apple could be facing a significant shortage of its highly popular 7-inch tablets, which could spell serious trouble for Apple's tablet sales in the quarters to come.

In this video, Fool contributor Andrew Tonner looks at the recent rumors and their possible implications for Apple investors as we head into Apple's most important quarter of the year.
