I have a Commodore 64C, monitor, floppy drive, and a pile of disks, I've used that once. I've two ZX Spectrum machines (one in a dk'tronics keyboard, nonfunctional) and a Spectrum 128, with 50 or so tapes and one of those Microdrives plus some cartridges.
My father is the same with DVDs, he has a couple of thousand. The dad of one of my friends has double that. His lounge has a wooden shelf hacked together, that thing stands floor-to-ceiling along one side of the room, wraps around a corner, and is packed solid with DVDs. Babylon 5, Red Dwarf, Monkey, the Goodies, Paint Your Wagon ("Gonna paint that wagon, gonna paint it good, we ain't braggin', we're gonna coat that wood"), the list goes on.
To me, my collecting and never doing anything with the items seems almost like a sickness. I still have all my University texts - I justify it to myself by quoting a friend of mine who said "I don't believe in selling textbooks, they might come in handy some day." They won't, most of them are more than a decade old, but I still can't bring myself to get rid of these books that cost me hundreds. It was hard enough dumping those ISA cards that were no use to anybody - and I still have a stack of 500 megabyte IDE drives somewhere.
I understand your tabs behaviour - I am the same, but once when I come to 90-ish, I start culling session to cut it to more reasonable number.
Now I want to get the Spectrum out for a play, but I expect I'll lie down until the urge passes!
Thinking I might do a re-cap on each of the machines, two of the capacitors on the Commodore are a little bulgy. It is a 30something year old machine, though!
