Just expanded the size?

What!!
Basically, if samsung brought a new fresh design with average software and hardware changes you would have been more impressed? As far as I care about, if someone is spending money on a phone, he would rather put money on a smartphone that has the best specs on the market than on a sexy phone. I find the S4 pleasant to the eye not as sexy as the xperia z and htc one but what is under that skin, nothing is compared to it.
Let me tell you the features of new Samsung Galaxy S4. Some are innovative and really cool to use in daily life.
* The phone size is little bit smaller, lighter and much stronger. They also increased 0.19" more with 441 PPI and non-pentile display.
* The innovative feature which gets ability to shoot images and videos from both rear and front facing cameras "at the same time."
* Air view with fingers, no need of S Pen or stylus.
* Now it supports any gloves for touch screen.
* Smart Scroll that helps to scroll through hand gestures.
* Eye tracking helps to up and down the page.
* Samsung bring the Infrared (IR) tech back. Now we can control TV from smartphone.
* Samsung Knox helps to separate personal and business use of the phone. Just like Blackberry 10.
* S Health will keep you record your diet.
* Group Play shares content with those around you.
* Samsung Smart Pause. That starts and pause the video while you move your head from the phone. (Amazing)
* Uber fast camera performance that takes 100 pictures in seconds.
And many more that I forgot... someone please tell.

I know by knowing the performance,features and display of Xperia Z people will definitely through their phone in water. That's why sony gave this feature. #JK
Jokes apart. That water proof body is only a safety feature like airbags on car. I personally don't prefer sharp sexy edges of SXZ, it makes uncomfortable to grip.
