I use an iPad for surfing, and for Roon to pick music to play through my stereo. Sometimes music is a background thing while I browse idly, or read or eat, but when I am listening properly I do it to the exclusion of everything else. Similarly, if I want to browse seriously or use a computer I go to a separate room where I use my iMac with a nice big screen at a desk. Stopped using a laptop years ago, and haven’t missed one, nor has my back, eyesight or fingers. Don’t use my phone for anything hardly, but have found an Apple Watch is more useful than I thought it would be. I talk to it rather than press buttons, and it is very handy. I can even use it to find my phone.
