It will be nice if a cellphone could return to be only a cellphone
Nowadays devices are everything but a cellphone… large things difficult keep in hand, battery duration shorter (a very annoying thing in my opinion), internet connectivity all the time (who knows what information are sent???).
Another very annoying thing is that there is a lot of useless things pre-installed and often you can’t get rid of that
Another thing I don’t like at all is the touchscreen… too complicated, often with slow responsiveness (unless you buy a very costly model). I still prefer to use a keyboard.
About the screen size, it is certainly nice to have a large display, mostly for people with hypermetropia, but the only way to do this is remove the keyboard… did I mention that I hate touchscreen?
