Top quality and steady. Battery removable and google navigation. All this a desaster for apple.
For me is iphone secondclass Chinaproduct from Foxconn.

Both the iPhone 5 and the Galaxy S III have features that appeal to business owners with a range of mobile needs. Some will prefer the iPhone for the benefits of iOS and the huge app selection, the more compact design, or even better cameras. Others will choose the Samsung's GSIII for the bigger display, expandable memory, replaceable battery or less restrictive operating system.

Don't Buy an iPhone 5 - Here's Why

Galaxy S3 is still the state of the art phone on the market.

Even though the phone has been making record sales, there are still quite a few people out there that have yet to purchase the phone. Here are a few reasons to purchase one.

Top Phone on the Market

If the rumors are true and the iPhone 5 is slated for a September 21 release date, then consumers still have to wait for over a month to upgrade their phone. Why not go with a phone that is available and provides a lot of features that the iPhone won't have. IPhone 5 is said to have a 4 inch screen. S3 has a 4.8 inch screen.

The hardware specs are pretty similar.
S3 has a larger screen.
S3 has expandable storage via microSD card (up to 64gb on top of the internal 16/32)
S3 runs Android OS, which allows for
* more customization without modification
* Google Maps instead of Apple Maps
* Google Voice, which works better than Siri
* Multiple app stores and more free versions of many apps
S3 won't be outdated when Samsung releases its next phone

Even better, you can find several other Android phones now that are more powerful than the iPhone 5. There's cheap and expensive options, varied sizes, and even choice for slider keyboards if you want.
