I use my phone all the time so things are a bit different for me.
@stepside showed me some things change when I turn my phone sideways but the only time I turn my phone sideways is when I look at photos or videos. Sucks for reading and typing though!
I actually went out and bought a laptop but I've become so use to my phone that I took the damn thing back mainly because my phone is so much more convenient and to be honest I kinda forgot how to use a laptop also lmao
Phone caused me problems with repetitive motion in the thumbs. Bought a tablet and Never use the Mac laptop anymore.
