I used to always buy Nokia phones, and use a Psion and then a Palm Pilot as a PDA. I have used a few Windows phones, the latest being a Nokia Windows 8 phone, but my choice has always been Apple iPhones.
Leica have now continued there relationship with Huawei and the new P10. For many people the phone has become their compact camera.
While a Leica fan, at least with their M range, I will not be getting rid of my iPhone just yet.
