There are products that are designed to bend. For example, sippy straws are far more effective that way.
What about smartphones? Should they bend? Well, if by bend you mean "flex" and they quickly snap back into form, then sure. In fact, smartphones would be much better with that kind of flexibility.
Now what if they bend, accidentally, and do not snap back into form?
Well, there are now more than 16,000 complaints across social media with the hashtag #bendgate that say the iPhone 6 Plus is being misshapen in pants pockets.
Yes, it seems that users are reporting that the aluminum-backed smartphone bent to a noticeable degree after being carried in users' pockets.
