The Galaxy S4 is launching on over 330 carriers in over 150 countries. The S4 is feature packed and has a proven track record of high performance. It improves on everything that made the Galaxy S3 sell millions. If you have an S3, you would probably still be satisfied with your current device but there are still billions of people who have never owned an S3 that would be enticed by the S4. When the S3 was released, there were also negative reactions on tech sites much like there is now but it turned out to be a huge success. Mark my word, the Galaxy S4 will sell over 100 million units within 12 months of its release.
