Revolutionary defined as "radically new or innovative; outside or beyond established procedure, principles, etc." You don't see the front facing speakers as radically new or innovative? If not, please explain.
HTC didn't come up with the concept of speakers that point at the user. The person who made the very
first speaker figured that part out almost immediately. "Hey, it's louder if I point it at me." Many other mobile devices have had speakers that point at the user for years. Here's a cell phone from 2008 with a front facing speaker:
New Casio Boulder Appears with Front-Facing Speaker (Phone Scoop)
I work for a company that makes mobile devices and all of them that have speakers are front facing.
It's just that in current cell phones it isn't the norm because it's difficult to fit in the form factor. HTC made it a point to emphasize audio performance (but that's not a first for cell phones, either) which differentiates itself from most other Android phones, but it's not any more revolutionary than a phone that emphasizes camera performance.
How many wireless devices have been created since their inception? Thousands, right? How many have front facing speakers? One. I would say that would carry a little bit more weight than "nice and all."
Only if the desire to both point the front of the phone at you while listening to music is seen as important. The Galaxy S4 has tons of new features not seen on phone before, but I wouldn't call any of them revolutionary. Just being unique isn't enough for something to be revolutionary or even useful. I almost never use the speaker in my phone (in fact, I use it the most when my phone is in my pocket and the speaker is facing out), so front facing speakers are barely "nice and all" for me. It's just another feature I don't care about. There are many others that think this way, too. There are some that don't, thought, and that's the definition of a niche.
Game Changer: "A newly introduced element or factor that changes an existing situation or activity in a significant way." You don't think the HTC One qualifies in this regard as a game changer? If not, please explain.
No because it's not changing a situation at all. "Slightly louder music when the phone is oriented a certain way" isn't all that significant, especially when using that speaker isn't used like that by many people. Some will like it and other companies may make phones with front facing speakers, but it won't be a "must have" feature.
OR, they had time and just decided, for whatever reason, to forego front facing speakers.
I wonder if the HTC One had been a monster success would that have made a difference in what other devices chose to do with design.
Don't both of those point to the front facing speakers not being game changing? If it really were revolutionary and game changing then the demand for the device would be through the roof and everyone would be copying it on all future designs.
It seems to me that you need to be the one to prove why it's revolutionary and game changing. There's no evidence that it has started any sort of revolution or changed any games. It's just a neat feature.
Do you think next year Samsung, LG, Motorola and other Android manufacturers will institute front facinng speakers on any of their upcoming devices?
Any? Perhaps. Definitely not on all or even a majority of devices, though. If it really were revolutionary then people would demand it on most devices. I just don't see the fidelity and volume of the built in speakers as being important enough to enough people. There's a physical limitation to how good and loud tiny speakers can sound that prevent them from being anything more than being only kind of important to some people.
