Besides speed, what would actually suck about surfing the internet back in the day compared to now?
My pick would be, dealing with the 'wild west' atmosphere. That being, before cyber bullying laws existed, you had bunches of people getting off scot-free with telling you to off yourself or call you a list of derogatory terms.
No mention of Mosaic (first web browser)? What sucked was you generally had to compile it yourself. That meant installing all the build tooling, building it, and turning it loose. Oh. Windows? Lol. No go. Gotta get an early version of Linux up and running first. That usually meant 20+ diskettes of Slackware installation.
But then you could surf in all the basic HTTP glory. It was a new world and it was awesome.
