Haha, mobile phones came with snake at the time. No one expected to be browsing the internet on them (which had barely passed into mainstream use). I remember around the time my dad's friend coming over with his work laptop (a rare thing at the time) to show us "the internet". Everyone just assumed a lowest common denominator resolution and got on with it!

My pet peeve was not being able to use 2 windows next to each other on my 1280x1024 screen because the UIs assumed full screen usage.

Phones - for sure, that's a modern development. But it's been more than a decade now, there are adult people who don't remember world without iPhones and Androids! Crazy... Myself, I started on Windows 98, but it's Windows XP (and Delphi) that defines my childhood.
