I can certainly understand why people would voice their opinions about how button placement on a phone can leave much to be desired. Afterall, we've come so far in terms of cell phone advancement that it is no longer just a phone, but a way of life and culture. I mean, seriously, people are calling it their "daily drivers" for crying out loud. But for me, I find it pure comedy that a 1 cm difference in the horizontal positioning of a power button on a phone that's 2.5 inches wide can really be this controversial. Especially funny when I read comments/reviews that said the placement would have been perfect if it was positioned at the center-top of the phone. But since it is 1 cm to the left, it could be possibly the "worst power button placement" in the history of mobile devices. Seriously, people?
I think we live in a world now where consumers like us are spoiled by the ever-so-competitive landscape of mobile devices and technology that the "make or break" of a phone could possibly come down to the human factor engineering of the placement of something as trivial as a home/power button. For me, as with many others, I can reach the power button just fine with my right hand (single). I don't see how someone can "comfortably" reach the power button if it was placed in the center and be "uncomfortable and awkward" in trying to reach a power button off-set 1 cm to the left. But when I'm at home or not driving or not at work and I'm just reaching to play around with my phone, I can easily hold it with my right hand and use my left index finger to power the phone on if I don't feel like "stretching" the limits of my right hand (I feel silly just saying that previous sentence). Afterall, we're talking about an action that would take all but what, 0.5 seconds to perform? Not exactly "strenuous" activity we're talking about here
Bottom line, in the grand scheme of things, mobile devices now have improved in such great leaps and bounds that it's a bit silly to think we're still having raging debates about button placement. Again, I agree that every person is entitled to their own opinions and to each their own in terms of what they like/dislike about the aesthetics of a phone. I happen to think the HTC One is a fabulous device and something trivial such as button placement should not nearly affect the overall quality of a phone as much as it has.
Another thing I'd like to point out is that these professional "reviewers" are paid to be critical of every minute detail because it's their job, simply put. They'd make lousy critics if they agreed or complimented everything about every device. It's kinda like how movie critics that would never give any film 100% on principle alone simply because doing so would discredit their entire reputation of being a critic, LOL. But at the end of the day, for the casual android fan/user like me, I'd gladly take an HTC One with the most awkward button layout ever imaginable over a phone with ergonomic perfection and lackluster performance in other areas. In short, I've never fully agreed that ergonomics should hold such a high weight in terms of reviewing the overall performance of a phone. I'm sure many will disagree and throw out the counter-argument about "then why are we even posting on android forums", and to that I would say, because I had some free time =)
