A side note is what a great phone the S3 was and still is. Mine has been outstanding for over a year and a half. Still as fast as the day I got it and able to run any app I throw at it. Nothing that has been released since has been enough to tempt me to upgrade.
It's no wonder the S3 was such a game changer for Samsung. Compared to the competition at the time, the iPhone 4S, it was in another league. It aged much better with its beautiful 4.8" screen, removable battery, and expandable storage. Yeah, it's plastic, but it feels sturdy and at least I haven't had to replace the the glass back 2 times like my sister had to on her iPhone 4S or the home button like my father did on his iPhone 4.
Here's hoping the S5 is something pretty amazing because I would certainly give Samsung another shot.
