For me going way back, it was exciting when I had to save a bit (but not too much!) for a new 512 DIMM, and when I opened the box and smelled the chip smell, put it in always worried I was going to fuck it up, and then computer literally felt faster that next boot...that was pretty fun!! Now it's like oh great $5k for a slab of stone that can do pretty much anything, neat. I still think computers are cool, just not particularly exciting.
