I’ll start: printers.
I bought an HP in March 2020 when my job went remote and HP bricked it remotely after only 100 pages because I wouldn’t sign up for their subscription program. Ended up trashing a perfectly good printer.
Luckily my library’s close by and I can print there remotely.
Projectors put out a lot of heat depending on what you’re looking for.
Any direct view screen at the size of your typical projected image will put out just as much heat. Those 80" panels do not stay cool.
