in what way does the iphone5 NOT compare with those phones? Let's see the S3 has the worst screen and second ugliest UI and design out of the bunch. HTC has the worst build quality and second worst customer service despite having the best designs. LG has the worst softwares and design and the worst customer support and also the worst battery life. Nokia Lumia has the worst app store in terms of quantity and quality. All of them have batteries that are much bigger than iphone5 yet they achieve similar or worse battery life. IN terms of bench marks iphone5 is on bar with those, lower in some tests but higher in others.
Yeah sure iPhone5 sucks.

Because for unknown reasons, people in the forums (the very vocal minority - the majority of people just buy the things and use them, instead of bitching around on the internet) are whining because "iOS is boring" (TM) and there is not enough "Change" (TM) in the OS or design of the device.
But they just don't understand that "Change" doesn't sell devices, being a great device does!
Apple innovated the smartphone sector when they released the iPhone, no other company has innovated in that sector since then.
Phablet with stylus?
That's not innovation, that is just a larger screen (Can you say Dell Streak?) and styli have been the norm for smartphones BEFORE the iPhone.
If you want to see what is caused by "Changes" just to change something that is not broken?
Windows Phone and Windows 8.
Windows Phone 7 had horrible sales and the sales of Windows 8 aren't that good either.
Windows 7, on the other hand, was nothing more than a perfected Windows Vista.
It had great sales.
Not because of changes - it lacked changes, it was just a newer variant of the same old Windows - but because it was the same old thing that has been around since Windows 95 - just perfected.
I dunno... the iPhone 4 and 4S were the EXACT SAME DESIGN. No one complained... Apple sold more 4S than all other iPhones combined.
Now... when Apple finally changed the design... made it out of aluminum instead of glass... and gave it a proper 16:9 screen... and LTE... now it's stale?
Sheesh...
Oh yeah, that was funny...
When the iPhone 4 was new, everybody whined that glass can break.
When the iPhone 5 was released, everybody whined that aluminium can dent.
When the iPhone 6 will be released and they switch to polycarbonate (which is not going to happen), everybody will whine that it can scratch.
With Apple, there will never be "Oh, it's a great device" - only "Hm, this sucks, that sucks, crApple has lost its edge"...
Oh, and now for something completely different:
To those that think that lowered part orders mean iPhone 5S in a few weeks/months:
Many mentioned that Apple will change every part of the internals BUT the display - please remember that OTHER rumors said that Apple will switch to a new TOUCH ON DISPLAY technology, getting rid of the Fruit Ninja error-prone In-Cell-Touch - and of course IGZO, that has been rumored for a year.
So the display is definitely something that will get changed.
Oh - and there's of course the case that we have seen "New iPhone will be released much earlier" stories for years.
The iPhone 5 has been released about three weeks earlier than the 4S - not 3 months.
And what would Apple change in an iPhone 5S?
Doesn't "S" stand for speed?
The CPU of the A6 is one of the fastest available, the GPU is also one of the fastest available (bested only by the Adreno 320 currently used in the LG devices - the Nexus 4 has thermal problems, so that its GPU is much slower than the one in the iPhone 5, the LG Optimus G won't sell well - LG devices never sold well, so they don't really matter in the market).
So, what would Apple improve to call a device released in march iPhone 5S?
Of course, they could switch the old PowerVR Series 5 GPU to a new Series 6 (Rogue) GPU - that should further increase the performance and add OpenGL ES 3.0 capability - but there's just no demand for a better GPU at the moment and also not in March - Galaxy S 4 will not be released before May (even though rumors suggest that it will be released much earlier - but that has been said in the past and never happened).
And as usual, the Tegra 4 lags behind and seems to barely reach the GPU performance of last generation's iPad (A6X) or even less, so that is no rival either.
