I have been looking for a phone to upgrade from my iPhone 5 for sometime.
On paper the S4 has a slight advantage in some areas but this is mostly illusory as the differences are so slight there is no real world impact.
I applaud HTC for trying to end the pointless pixel war. As a amateur photographer I can say that all mobile phone cameras are cr@p so why have bigger files which just waste space ?
However once the phones are in your hand it's another story. The One is just beautiful. It it a phone you really want to just pickup.
I went to buy a S4 and came out with a One, for pretty much the same price.
The S4 is not only plastic fantastic but the design is still stuck in the iPhone 3 groove which Samsung originally copied.
The S4 is a great phone, but for me the One is almost perfect. The screen size and weight, the design, the georgeous screen, the software, the speed.
Sure, nothing is perfect, the One get a bit warm in use, it would be nice to have a SD card slot, a polishing cloth would be nice in the box etc. but this really feels like sniping.
