These days you can come across people saying they prefer playing games on their smartphone rather than PC. Used to have a game or two on my smartphone, but not anymore. I'm insisting on an older low-end model from 2014 and only have essentials. Was actually more into mobile games back in the era of J2ME games on dumb phones. I do like using phone for reading forums and such content on the internet, just like not being confined to that chair near computer.
Since WiFi was mentioned, in my experience, speeds still suck even when you're right near the access point. It may not matter as much for web browsing, but good 'ol cable is hard to beat. And I think it would be better if air wasn't as crowded with radio signals as it is.
About devices being smarter and whether humans still evolve, logically, I would think they make us lazier. Devices' designers on the other hand, well they had put effort into them to make them work, right? I admit I'm more on stagnating side, not sure if devices are to blame or not. I've had more contact with computers throughout my life than people, sooo... I still remember a classmate from elementary school's earlier years telling me he thought computer was my only friend.
