Amazon has today announced that its in-app purchasing service, which is already available on the company’s Kindle Fire tablet and other Android devices, is coming to Mac, PC, and web games. This will allow developers to take advantage of Amazon’s service on those platforms to provide their customers with a new way to purchase additional content using their credit card or virtual Amazon currency.

While Amazon isn’t the first company to offer an in-app purchasing system, its service does come with some advantages that developers may not get from its rivals. One of those advantages is that their content will be available via Amazon.com.

Just a few weeks ago, we reported that Samsung and Apple were the only two smartphone manufacturers seeing growth in the United States, and that the pair were slowly eating away at their rivals’ market share. But when you take old-fashioned feature phones into account, the situation looks a little different.

New data from Counterpoint Research suggests that strong December sales have helped LG overtake Apple to claim the second-largest stake of the U.S. phone market. As you might expect, Samsung is still way ahead in first.

Apple has made the iPhone more enterprise-friendly with almost every release of iOS, but some might say the company’s popular smartphone still isn’t ideal for business. When I say “some,” I mean Samsung. The Korean company just released a strange new advert to promote the enterprise features of its Galaxy S III and Galaxy Note II, and it couldn’t help but bash the iPhone and even BlackBerry devices at the same time.

Rumors surrounding the Sony Xperia Tablet Z first surfaced last week, and we expected Sony to confirm them at Mobile World Congress in Barcelona next month. But in Japan on Monday morning, the new flagship tablet was unveiled. And boy, does it look good.

If you believe recent reports and predictions from analysts, Apple must make its iPhone cheaper or introduce a low-cost model if it wants to compete with Samsung going forward. The Korean company currently boasts the largest smartphone market share in the United States, and its lead is expected to increase throughout 2013. But did you know that Apple has actually sold more devices? 88 million more, in fact.

Raymond James analyst Tavis McCourt has been comparing Apple’s cumulative smartphone sales with Samsung’s, and it appears the Cupertino company’s iPhone outsold the Galaxy S and Galaxy Note lines 219 million to 131 million.
