I'm glad for you, and I'm not trying to argue with you. All I am doing is indicating what I think is a healthy attitude to have when collecting computers. I do my share of collecting worthless pieces of electronics (mostly Macs), but I also try not to get emotionally attached to the idea that they have some intrinsic worth.

It's awesome for you that you can sell your 5xx AIOs for such high prices. I think this is an aberration, though, and probably not a price the market will sustain. These machines are without intrinsic value, and I find it odd that anyone would pay more than a couple tens of dollars for one. As some have already pointed out, these sales may be the result of selling to young adults who have some disposable income and who are experiencing nostalgia for the computers they grew up with. If so, that trend won't last. I encourage you to sell as many of them as possible as quickly as possible (especially while the US dollar is in the tank).

Peace,

Drew
