My Motorola Android phone has no battery removal for replacement.
I had only one upgrade to its operating system, and what it gained in operational efficiency it lost in camera performance.
My Samsung tablet had two upgrades in OS. What I gained on battery lasting longer I lost on battery charging time. The tablet can last 12 hours no sweat, even with YouTube videos, but it takes much longer now to charge it; say from 20% to 100% it takes now roughly six hours...before it took only three hours.
You win some, you lose some.
If you buy a premium phone or tablet...iPhone or iPad (Apple), you get all the upgrades. Lol, Apple is not number one for nothing.
I had LG, have Motorola, Samsung and Sony, and my friends and family have Apple products and others Microsoft products, Google...my smartest friends and family members are the ones between and above.
The best looking people, the youngest use Apple, the elders use Microsoft, and the brightest use both. ...From my own entourage, but if I move to the next street corner it could be the total opposite.
It is extraordinary today the reliance we have with our electronic devices.
We live artificially with intelligent access to the world in the palm of our hand. When we were kids we were relating to our parents and teachers knowledge, plus what we heard on the AM radio and what we saw on our cathode black and white tube TVs.
Today we have the world encyclopedia not in libraries but inside our phones.
The phones we had when we were kids were with coiled wires and huge bricks, with an analog round dialing ring. Lol
Fifty years from now, when we're all gone, unless some of you are under fifty and with a steel health that makes you almost immortal...till age 100 or so, can you imagine...
They will use only their mind to communicate and get all answers to all questions. No more prehistoric devices like iPhones and Samsung androids.
They will live in the new age of flying cars and rockets. ...And only from mind energy operated. The human race in 200 years from now will be so advanced that they won't need Twitter and Facebook any more. That, is progress.
Sensible omission of the paperless office prediction.
