Tell me with a straight face that you think S-Translate is actually going to work reliably. I mean S-voice was great, wasn't it? (sarcasm). And it's cloud based, so you're outta luck with no signal/wifi. Definitely would never be in a situation when I'll be outta the country and depending on my S4 for translation.
Dual Camera is situational at best, but it is one of the few features that may have some uses.
S-Health is just lol honestly.
Most of the features can be better accomplished in some other way, or is completely unnecessary to have. I'm certainly skeptical it will even all work as advertised. Even if it does, it won't ever really be useful. When are you ever going to be around 5 other SIV users, and want to broadcast some sound, and have the time/drive to organize an All cast? It's completely worthless. It's fairly obvious that they're jam-packed in there for advertising reasons. The public will swallow them up. But I know right now that they're not interesting to me.
