Personally I dont hve a mobile phone. Being the corporate whore that I am, my company gave me one for back in the day when I was on call so I could be contacted easily.
These days I mainly use it for when I travel for work, or work form home.
If I do leave this company I will probably ask to have the contract and the phone ported over to me so I can keep it, as gradually over the years friends and family contact me on that phone.
A surprisingly pessimistic post from Mr Brightside. AKA Who 2 ?
Allow me to adress the David Icke like response in your post Dear Doctor.
If these bloody modern day doomsday merchants and luddites had thier way, we would all be grovelling about in the mud on the edge of a forest trying to eek a living from the land and would starve if the crops failed.
Ok, so as a rule I generally stay on the straight and narrow path but I get away with as much as I can, so I really dont worry too much about the long arm of the law. But I will do whatever it takes to survive if push came to shove.
I am lucky enough to have not been put into that position, but god forbid if I was, I woudl maybe knock a coppers helmet off for a warm night in the cell and a free meal, it wont cost me anytjong as I wont have anything to pay with.
Here is the positive side of my mobile phone ownership and subsribing to Google services and GMail.
My phone is an all in one device which is very useful for travelling and everyday use, although it is not my constant companion that demands my attention every minute of the day, I check it when I can be bothered.
Its a clock, world clock and alarm clock. Its a great camera and I can use the flash as a very bright torch with the ability for hours of use. I can pull up my photos anytime I want to look at them and share them with others.
I can use it like a computer so browse the web and compose, send and recive emails,
its a calculator so I can do quick currency conversions when purchasing abroad and any other calculations I may have to make.
Its a music and movie player and I can keep those on my phone or pull them off the web.
I can text family and friends and I can even have a live face to face video conversation. ( this was the stuff of Sci - fi 50 years ago )
Its a compass, its a GPS device and its a Sat Nav system that can guide me to anyhere.
If I need to have a conversation with Johhny foreigner and the bugger hasnt bothered to learn English, I can speak into my phone and he can then listen to the traslation, then he speaks back to me in his native tounge and it translates it back to me. Again, the stuff of Sci - Fi books years ago.
Its a document storage device ( no trees harmed )
The phone automatically connects to the car, so I can make or take calls if I want to or port the music or sat nav instructions from my phone to the car audio system. The car has Sat Nav, but its useless here in Wales.
Google tracks me and my movements, as such when I wake up in the morning it will tell me how long it will take to get to work and the traffic conditions. It also tells me what the weather is going to be like. I dont even have to unlock the phone for that, the are just passive messages on the screen that I see as I turn off the alarm. Likewise at the end of a working day it will tell me how long to get home and where any congestion may be and offer me alternative routes.
I contribute to Google Guides, so after I visit a place it will ask me some questions and I can submit my experience and any photos I may have taken. These reveiws go out on the internet like tripadvisor, so hopefully my contributions help, and like wise other peoples contributions help me decide if a place is worth visiting or not, after carefully studying what people say.
I have all my travel documents on my phone which I also send to my GMail. Gmail even scans those documents and will send me a message to advise me to book a taxi a few days before I am due to travel and even alerts me a few hours before I am due to travel, just in case I forgot. Which I possibly could do as I do travel a lot.
Having Gmail is great because I can access it on any device and retrieve those documents if I lost my phone.
I can also access any pictures, films or music I have stored on GDrive from any device too.
My phone will automatically upload them to my Gdrive so I dont even have to remember to do that.
I can do all my banking on this device as well.
Oh yes, and I can make and recive phone calls and choose wether or not I can be bothered to receive or answer any calls.
Now, while some people may think all this tracking is a bad idea, I can see the positive side of this, and yes even having a micro chip implanted if it came to it. Why ?
Ok, if I got lost I can be found. If eveyone else is in the same position eveybody knows where everybody is. That information can be logged. Now, if anything happens to anyone then it wont be too hard to track the perputrator.
I could in effect send one of my children to the other side of the world without having to accompany them. The phone will be able to guide them along and hold all necessary documents and ID. Who is going to harm them if they know they cant get away with it ?
So in the future, you can commit a crime against you fellow man, but you will be caught.
Is having the ability NOT to commit a crime a bad idea ? read on..
Maybe its asking too much of people to treat eveyone as they want to be treated, but you can change society as has been proved time and time again, so if anyone has any smart ideas about not doing that we can always show them the past where things were not so good just to make them think....
Lets look to the future where instead of incompetant out of touch arrogant oaf's running things,
we have now passed many day to day aspects of life that need to be controlled over to computers.
computers who's syetems are transparent and open to scrutiny by all.
We could have autonomous cars, which means I no longer need to own a car and all the expense that entails. the system knows and has learned my movements, so a car will just turn up to take me to work, ot will then make several other journeys during the day for other people and families, not sit in a car park or driveway for 99 % of its life.
suddenly roads are a lot less congested. And traqffic will run more smoothly as the main computer system knows the present and future movements of evey vehicle.
We can even have robots doing all the work, If you have travelled to a singapore Hotel, or visited a workplace that is already strarting to happen.
But all the things mankind REALLY NEEDS can be manufactured by robots so can farming and the processing and transportation of goods and materials.
We can now have more leaisure time and have the ability to travel around the world and do whatever, wherever it is needed, we would then not need a single house to tie us down to a geographic location that we feel compelled to return to.
You coudl if you want, now there is a choice though.
The possibilities are endless, Elecrons connecting and guiding eveyone. People run the world, eveyone contributes and we make mankind the responsibility of all, not hand over our freedom and power to those who think they know better or muscle thier way in.. As is proven, we get Royally F*ucked over if we allow that.
All information and knowledge out in the open, a world were great ideas are embraced and not held back by greed or alterior motives.
We are all becoming aware that we cannot continue as we are doing, so change will have to come, as this world changes and is giving us the wake up call we all need. Adapt or Perish..
Where we are today, we stand on the brink of all of that. We need more positive energy to acellerate the process.
This world and its inhabitatants will all benefit. I still believe we are yet to reach our epoch, the Golden age..
After a few hundred years of that happening perhaps we will no longer need to be here.
After all, being human, Heaven would get boring after a while and we would need new challenges.
Jesus thats deep...
Don't look back. That's not the direction you are travelling towards.
I just ditched my i-phone for a Samsung Galaxy and bought myself a nice new protective case and because it does QI charging I also purched one of those as well, bloody thing is useless even though it is also a Samsung original QI charger, problem is that the leather on my new case is too thick to allow the charger to work so back to a plug in cable or buy another thinner case. 
Experience is not what happens to you;
Many new phones can equal them or even beat them hands down especially with all the Android Apps available for free download, Samsung and Huawei are making big inroads although the latter may become less popular if current American politics holds sway. I use most of the features you mention, but in addition I can remotely view my back garden, drive and my living room anywhere I am in the world just by accessing the security cameras around my home via my phone and see what is happening there in real time. I can also use my Alexa App on my phone to turn on or off various devices in my home such as lamps, my mate has even set up his roller shutter garage door to operate via that particular App and on one occasion he was away on holiday and I wanted to use his small lathe and as I stood outside his garage he opened it up to let me inside.
