It's become something of a tradition for Apple to mark major milestones in iTunes downloading by offering prizes to the person who actually hits the number. For example, when the online music store sold its 500 millionth song back in 2005, the person who made the download was awarded ten iPods, a $10,000 iTunes gift card and an all-expenses paid trip to see Coldplay.

Since then, Apple has introduced several more devices, including the iPad and the iPhone, and with them has come a serious expansion of iTunes' offerings, most notably apps.

Apple is very quickly approaching their 500 billionth app download, and to celebrate they'll be giving away a $10,000 iTunes gift card to the person who pushes them over the milestone.

The tech giant also released a list of the most popular apps of all time. Some of those listed are hardly surprising, like Instagram and Skype for iPad, but the inclusion of Pages, Apple's office productivity suite, is further evidence that the iPad and iPhone aren't just toys, but serious devices that businesspeople will find indispensable in their daily operations.

If you're looking to take advantage of the exciting offerings that Apple has available in the iTunes store, or if you're want to upgrade your existing Apple devices so that you can use the latest and most advanced apps, please take a moment to peruse the PortableOne online store. There you can find the Apple iPad 4 and iPad mini tablets, complete with WiFi and 3G connections.
