[citation][nom]hasten[/nom]Nothing but advertising to keep up with the joneses. Christ, 1080p hardly matters on anything less than 32" unless you are sitting one foot away... or of course high res gaming. For some reason I don't think there will be much a difference for angry birds on that 5" screen. These companies need to stop with the gimmicks and focus on usability and battery life.[/citation]
1080p is not a needed feature, but you can easily tell the difference. Go look at the DNA screen vs all other 720 phones out right now. You will notice the difference between the screens easily. So 1080p isn't a gimmick, rather just a premium feature that will be available for most if not all high-end phones starting in 2013. Also, the S4 will come with the Exynos 5 chips that are much more energy efficient, and will probably come with a battery close to 3000 mAh. If you look at the S1 then S2 and S3, they have upgraded the batteries each generation. Also, all of Samsung's Galaxy phones have come with removable batteries, meaning you can easily just buy a 3500-5500 mAh battery online and replace it.
