Ok. Back to reality. The i6 is a great device and the GS6 will be a great one as well. The Apple OS is very lean and well organized. The Android with slimmed down TouchWiz on top is a more customizable ecosystem that does a lot of things as good or better especially true multi-tasking. Both meet very different needs where Apple ecosystem is more packaged and restrictive appealing to people who like slick and quick without having to think about it. In the last two years or so, this past year in particular, Apple started playing catch up adding a larger screen and NFC for example. While large steps for Apple, these would be considered incremental by Android standards. At the end of the day, it doesn't matter what you read on this site. It is up to you to take ownership land and make your decision based upon testing and facts. After the GS6, Apple will be further behind.
