Dial Up. Yeah I know the sound and I know the time it took to load anything with. But it’s something I won’t ever miss having. I would much rather be on a 1MB connection if I had to choose between that or dial up ever again. I also hated how easy it was to be kicked off, if anyone called the phone, you were off it in seconds.
CRTs.
But you need a whole second desk to fit them and they make that awful buzzing sound!
