Style has 2 front facing speakers
I hear what others say here about the size. The Style is actually narrower than the Force. Handle both and there's not a right lot between them. I'd think if you could handle the Force screen then doubt you'd struggle with the Style's. It is big and beautiful

I have big hands so find either manageable. Really hope they don't go bigger - but said that when I got the 2014 moto x
I wasn't expecting much of the Style's battery when I bought it but it has surprised me. I'd call myself a medium user as opposed to heavy, whatever either are. Maybe even light some days. Couple of light days, maybe an hour or more of screen on time, an hour of calls etc etc and I've gone 2 days without charging. It sips practically nothing over night. 11pm to 5-30am dropped my battery 4%. Similar use with the bigger battery of the Play and never got 2 full days. Every bodies milage will vary.
Apart from the £500 price tag to start with I was concerned the display is no brighter at max setting than the 2014 moto x. That was a problem outdoors on bright days, more so in summer. I may be wrong though.
