I have a Galaxy S5 that I will be taking back to the store since we haven't been able to get root on it yet, fairly satisfied with the phone.
I had an S3 and then a HTC Thunderbolt before that, both with removable batteries.
Removable batteries have been a huge pro for me, I am often very hard on battery using bluetooth and playing media for 12 hours at a time away from charger.
Really other than being a little tall the battery is what is keeping me away from the M8.
What options does a guy have to combat a non replaceable battery? I know the little pocket power cells have come a long way, and I currently always carry a spare battery now so maybe that is a lateral change. Are there some of those that charge very fast?
I tend to keep phones running a LONG time and pass them down to wife/kids and removable battery has always been a big pro to that.
