it was a fever dream but it was a pretty snazzy period, early 2000s baby here, grew up with stuff pertaining to fruitiger aero.
Strong memories I'd have would be going to my school's library to use the computers which were running Windows XP, not sure why but I really liked using the PCs to play educational games back then. I had one of those nokia flip phones which was passed down to me from my mother and It rocked! Had my hands on a blackberry and a nokia brick phone before eventually getting an Iphone 4. Can't forget owning a Nintendo DS lite which was alsp my first handheld gaming console.
The cons would be that the internet was terribly slow, we went through the Asian financial crisis & well not having as much freedom as I have now but I wouldn't say it was that bad since I had no responsibility and had all time to be a kid.
As for Windows Vista, never had a PC at home so it was literally Windows XP and then a jump to Windows 7 & 8.1. The only times I saw Windows Vista running was on the laptops owned by my teacher at school, that was about it.
