Only reason I still own a computer is if I need to print something. As soon as I figure out how to get the phone to talk to the printer I can let the old laptop die off 😁I think one of the reasons that forums are dying out is that like you many people are going phone only. I access forums both through my phone as well as a computer with a pretty large screen. The experience is 1000% better on the computer. First, a lot of information doesn't show up on a phone. The big thing however is that pics and vidoes just aren't the same on the tiny screen of a phone. I guess it depends on what you come to a forum for. I recently watched some of Ridefreak 's videos which have some great music in them. I put them on the big screen and put on my headphones and enjoyed.
I know I can show videos from my phone on my TV but I rarely do that.
I Bluetooth everything off the phone. Don't mess with videos much. I'll let a documentary play in the background when I'm in the shop or cooking. Not in the house much and haven't really turned on a TV in about 10 years.
