The subject of hotly contested scientific debate, not to mention a smackdown from AMOLED-loving Samsung, the Retina Display lauds it over the 3GS. The 960 x 640 display looks gorgeous, rendering colours sharper and deeper. See this and doubtless you’ll want to jettison your 3GS straight away.
2 A4 processor
The same processor as found on the iPad means newer, speedier apps which will be dedicated to the iPhone 4. Think iMovie, which will only work on the new device. It’s super-quick and hopes to give Qualcomm’s Snapdragon a beating.
3 Slimline design
Design is king at Apple, and the iPhone 4 certainly breaks the mould when compared to other headline gadgets. For a start, there’s a break in the metal band, which Steve Jobs claims is all about connectivity (of which more later). At 9.3mm, Apple says this is the slimmest smartphone going and it certainly does well to make the iPhone 3GS look podgy by comparison.
4 Glass back
This is a smooth move and one which means Apple has been able to bypass the issue of coupling neat design with proper connectivity. Where the HTC Legend sullies its looks with a plastic mould on the back, Apple has gone for a glass case to aid 3G and wireless skills, making the iPhone 4 look seamless.
Ok, this is an iOS 4 feature. But it’s no less important for its inclusion. Once again, this is another feature that should have been there from the start, with Jobs claiming only now will it not hammer battery life. The way you switch between apps is bested only by Palm’s ace webOS.
6 Stainless steel band
That steel band might have a most un-Apple like break in it. But the fact that it acts as the iPhone 4’s two antennas is smart. Apple also reckons it’ll toughen the phone up. So why it feels the need to flog pricey but colourful protectors for it remains to be seen. It gives the iPhone 4 back some of that style from the original model.
7 Five megapixel camera
The camera boost is a big deal. Steve Jobs says it’s not about megapixels, but in this case it is. The iPhone’s camera has needed this boost since day one and the inclusion of an LED flash, as well as the backside illumination sensor finally means it’ll work when lighting isn’t perfect. A more than welcome addition.
8 Two microphones
Suppressing nasty ambient noise by having two mics is nothing new, but it will help the iPhone get over complaints that it’s not been fully up-to-scratch when doing the basics well. It’s also set to make FaceTime calls better, although of course you’ll need an iPhone 4-owning pal for that to play nice.
Apple didn’t invent video calling, as much as it would like to claim it has with FaceTime. But the advent of video calling on the world’s most sought-after handset is welcome. At the keynote it looked sharp. And the fact that it utilises both cameras makes it unique and worth getting het up about. This is a dedicated iPhone 4 feature and will be Wi-Fi only to begin with.
Sounds like a gimmick? Hmm, maybe. But then so did the accelerometer when we first saw it way back when. The Jenga-like game Steve Jobs showed off last week proves that this will be a hit with novelty game makers looking to make a killing in the App Store.
