I use my two phones, an S21+ and an S22+, almost exclusively for online stuff. I only use my Intel NUC connected to the TV for watching serials and movies or when a website isn't optimized for mobiles.
the screens are not 'tiny' as you claim and I have almost zero issues using either phone as my daily driver. but unlike this mob here I feel the need for speed so refuse to use anything other than a 5G data connection when I'm not on the home WiFi (True fiber 500/500).
