Personally I avoid smartphones and tablets. I had a tablet briefly, but it just felt incredibly shallow. Instead I use a blackberry-style phone for calls and texts and a desktop computer for everything else. Also a Kindle Paperwhite, which is basically a tablet optimized for the sorts of content I prefer to consume (books).
Lsur said that they tend to avoid desktop GUI based Operating systems for PC’s, like all modern versions of windows, what’s your opinion on such operating systems as they seem just as shallow as Android or IOS. But they are significantly more user friendly then text based operating systems.
Desktop GUIs are simple, but a click or three can open software that’s complex enough not to annoy me. Part of it is the screen; you can fit much more information on a large screen (obviously). Part of it is the input; keyboard and mouse gives you many more potential actions at any time than a touchscreen (given realistic limits). I will admit I disliked the Windows model at first, but I quickly realized that it worked pretty well.
