After using my S7 Edge for two days, I've forgotten my S5 that I was sure would be my last smart phone. Yes, it needs to be cased ASAP, slick as it is. The fact is, you are either an iPhone user or not. If you are, no other phone will do. My brother (Apple to the core) was over yesterday, and the phone sat on the desk between us as we talked. He couldn't even bring himself to pick it up. I said nothing about it, just to see if after living in his walled garden for so long might evoke some curiosity, but nope. So, for me it's a great upgrade, and may well be my last phone. I switched providers in the process, so it's a bit like starting over. And, FWIW, Android is now a great OS.I just hope that the next iteration doesn't screw up the advances Marshmallow has brought. All in all, well done Samsung.
Update: My Edge is in a Caseology Wavelength case now, and feels much safer in hand now, without much thickness added. Nice, having a phone with enough storage that with the OS and all the apps I'll likely ever need, I still have 60% of it left.
