If u look at full hd its res comes in at 1920 × 1080 with a pixel density of 2,073,600.
Where 2K which res is 2560 × 1440 with a pixel density of 3,686,400

There is a difference between full hd and 2K as you can see the pizel density is allot more whether you would notice this on a phone is entirely up to how good your eyes are but for the most part it will look allot brighter that's basically it.
So based on this comment I then am in agreement with you JStrike can't believe I just said that lol

1080p is also considered 2K. It would be better to rather refer to 1080p or 1440p to avoid confusion.
 
Just with my experience with having a s3 witch has a res of 720 x 1280 and comparing it side by side to the s4 which has a res of 1920x1080 it looks allot brighter and clearer to me.

It's brighter because they made the screen itself is brighter - not because it has a higher res.

Unless i'm wrong, 300 pixels per inch is supposedly the density at which the human eye cannot see individual pixels. 1080p on a 42" TV and 1080p on a 4.7 phone is completely different densities. What you calculated above is not the density but the resolution.

This also means that 4K is on a phone is completely pointless but really awesome on a massive TV.

It is an improvement on an already awesome phone franchise. The S4 is brilliant! The S5 looks even better! This negativity is interesting...

They're called opinions. What you call negativity is simply people voicing their preference regarding aesthetics. It seems a majority of people do not find the design very appealing. (a large number preferring the S4)
I suppose I could say your exuberance, complete with exclamation marks, is peculiar considering the mass consensus, but it's just your opinion and equally as valid.

It's not pointless to go over 500ppi. The eye might not detect a big difference but well... why not do it? It's just that the flipside to increased screen resolution is the GPU and power requirements go through the roof. From 720p to 1080p is already a big jump; from 1920 to 2560 would slow down the gaming and ui performance unless the GPU was also improved to match.

And if the tradeoff between the increasingly hard to distinguish pixel density, and phone performance, has to be made, I'd tend to lean towards keeping a manageable resolution. So long story short - what Samsung did here is quite logical, and it was absurd to expect them to have doubled it yet again.
 
Anandtech has a characteristically excellent article on the pixel density question:

http://www.anandtech.com/show/7743/the-pixel-density-race-and-its-technical-merits

While going as far as possible in PPD makes sense for applications where power is no object, the mobile space is strongly driven by power efficiency and a need to balance both performance and power efficiency, and when display is the single largest consumer of battery in any smartphone, it seems to be the most obvious place to focus on for battery life gains. While 1440p will undoubtedly make sense for certain cases, it seems hard to justify such a high resolution within the confines of a phone, and that’s before 4K displays come into the equation. While no one can really say that reaching 600 PPI is purely for the sake of marketing, going any further is almost guaranteed to be for marketing purposes.

Interesting to see Samsung with their own hands-on review, ahem... Actually good to have a company enlighten the consumer market, but the real motive in my opinion is to camp the reviewers with their independent hands-on reviews which may bring some negative comments to light.
