I have vivid memories of my Win 95 computer that came preinstalled. I had to buy a bunch of empty floppies and spend what felt like an eternity just inserting it one after another so I would get my set of Windows installation disks.
I was 15 when it released and I had pre-ordered it on CD from Babbage's. The local Babbage's has previously tried to scam me out of a modem before, so it was no surprise when they gave me the wrong edition. I get home (which was about 45 min away and I didn't have a driver's license yet) and realize they gave me floppies. Said screw it, installed (going thru the painful process of disk swapping), then returned the damn thing the next week. Luckily this was before activation keys were a thing.
