This phone is what the original Galaxy S4 should've been, minus the extremely outdated hardware keys (I wouldn't buy it just for that) and with the S4's 13MP camera. Samsung really missed a golden opportunity me thinks. For all the flack the original S4 gets when compared to a One for a plastic design, at least people would be able to say their phone is waterproof. The original S4 is already on track to be one of the best selling Android phones of all time, but with Samsung's marketing muscle behind showing everyone they have a waterproof phone, there's no doubt in my mind anyway, it would've sold more than whatever the GS4 goes on to sell. It would've been like those with the iPhone 4/4S upgrading to an i5, instead of those with S3s staying put.
I'm a sucker for the color though and that's why I prefer AMOLED to TFT, that's just me though. But man, what could've been...
This phone will also cost more than the original S4, so there is that.
