For example, my wife, she is primarily on her phone as a computing device. Only recently after buying a Mac Mini and a Cricut is she back to using a standard computer. She might borrow my laptop for online shopping just so she can open 50 windows and 80 tabs to consume all available memory on my Macbook Air, but that's probably because Safari on iOS has sane tab caps.
I also know that games predominantly for PC / Web have become predominantly mobile over the years. There's a reason Roblox plays on your phone and tablet. You might not have the specs for a gaming machine, but your iPhone / iPad / Android definitely do.
