I would guess eventually certain computers, and maybe computer parts and even complete programs or games will be collectible. If I was so inclined (and I'm not) I'd stockpile early Apples, PC Jrs, the first run of IBM PCs, Lotus 1-2-3, early Ultima games with all documentation and maps, etc. for twenty years or so.
If you are asking will such a "collectible" be worth substantially more in one year or three years, then I doubt it. I think you will need both rarity and nostalgia to kick in first. But these are just my guesses.
