But then what would people have to complain about?
The stuff people nitpick gets more obscure as the iPhone evolves, so I can only imagine what the next "-gate" will be.
The One has a lot of stuff going for it, but IMO this is the best feature of the whole phone. Until you've used a device with forward facing speakers, you don't realise how great it is.
Does it pose an issue with hearing the phone ring in your pocket? The face of my phone generally faces my thigh and, especially when sitting, it can get pressed against it pretty well.
