Imma be honest with you. I would go for something like the Quest 2 as its more flexible IMO. It being able to be a standalone headset is super fucking nice and handy, then worst case if you already have a computer you can use it in conjunction with your computer for more games, better framerates, etc

the hell does "retina level display" even mean? Are they trying to compare the clarity of the screens to Apple Retina displays or is something else entirely?

A lot of these PCs are normal consumer computers that were improperly wiped when sold or stolen devices with activation lock. Either way its still e-waste and a huge issue.
