Here's one thing to add to things I hate about collecting:
The last 3 consoles I bought, I had/have to repair.
The SMS had to be opened up and have the voltage regulator replaced. Not a tough fix but still annoying.
I have to open my Vectrex's controller to figure out why the 4 button doesn't work.
And now the Virtual Boy I just got, which was working perfectly last week, is starting to display scanlines and other crap in the left eye display, so I have to fix that (apparently by taking the display cable and putting it in the oven for a minute or 2), since playing with the left eye closed is all sorts of lame.
I guess modern gaming isn't any better in that respect, even worse in most cases, but it's still annoying to repair this stuff (you never know where these old consoles went, so you never know how much someone else may have mistreated his stuff).
