With iPhone 6 launch event coming closer, more rumors keep pouring in. Today there were a couple of rumors on iPhone 6 via GigaOm. The first one was about how the Apple logo on the back of the iPhone 6 might not be a cut out with light shining through, but rather made of solid metal (Liquidmetal?). While this is purely ornamental, the second, related rumor was more interesting. Apple has always tried to make its devices more compact and portable, irrespective of their primary purpose, from the iPods to the recent Mac Pros. Its ideology always has been that any product should only be as bulky as is absoultely necessary. It famously abandons technology that it deems too archaic with its newer generation products, like the DVD drive and ethernet port on the MacBook Pros to enable this 'compacting' of its products. Some of these almost always end up being controversial though, in the long run seem to make sense (remember the uproar initially when the iPhone came with a non-removable battery or the first time when the Retina Macbook Pros could not be upgraded post purchase with more RAM or hard rive capacity).
With the iPhone, almost every new generation (not the "S" upgrade) has seen thinner, more compact design changes, even making iPhone 5 (and 5S) almost too thin to hold, comfortably. A lot of people have been calling out Apple on this, saying it puts too much importance on making its iPhone thinner and hence sacrificing potential features that could have existed, had the iPhone not thinned down, so much. With the iPhone 6, if the rumors are right, Apple is still following the same trend, as the pictures of leaked dummies have shown the iPhone 6 to be considerably thinner than the iPhone 5. Though I don't agree on all these criticisms, I do have to agree on a couple of them. For example I would on any day, prefer the iPhone 5 (or 5S) to be as thick as the iPhone 4 (or 4S) if that enabled it to have a much better battery life (thicker iPhone 5 implies bigger battery). The same way the limitation with smartphone cameras are that they have to be crammed in very thin chassis and if there is anything that cameras like, for taking better pictures, its longer lens lengths or thicker chassis. So thinner iPhone generally means that a sacrifice is needed on the camera's hardware capability that Apple has to overcome through its software modifications. Again I would prefer an iPhone 5 as thick as an iPhone 4 if that results in a much better camera lens.
But Apple can be adamant sometimes (what??). So far it has not paid attention to these criticisms and has continued to thin down the iPhones even further. However the second part of this rumor suggests that Apple might come up with a design for iPhone 6's camera, where there might be a slight protrusion (again Liquidmetal?) around the camera, to enable only the camera part of the iPhone 6 to be thicker, hence be much better. If this is true, it is a significant deviation from Apple's design principles of making all its products flush with uniform flawless design, like the unibody MacBooks. But if there is anything that we have learnt form Apple, its that it doesn't care about retreating its past principles/philosophies, if that deviation is well justified. So if at all this design ends up on the iPhone 6, that would enable a better camera on a thinner iPhone body, with the compromise being a tiny flawed surface on the otherwise perfect iPhone.
