After the S4 came out, I expected the S5 to be also mehhh. I'm a little disappointed that the phone is bigger and slightly thicker. But I guess I shouldn't be surprised, since it has additional sensors. I'm not sure how useful a heart rate sensor will be. But I guess it's cool for those that need it. And that metal edge and faux leather back looks bad. But I guess that doesn't matter since most people slap on a case.
I'll wait until the reviews come out. I'm curious about camera performance. No one has confirmed whether or not the S5 has the new ISOCELL camera sensor. If not, then I'll probably pass. Might get a Sony Xperia instead.
Also, I must say that the Galaxy Gear Fit is the nicest looking smart watch I've seen so far. I don't have any use for it, but it's cool Samsung is offering different watches for different needs.
