Curious, why were you a fanboy? Is it like rooting for team red and all the fun that goes into it? Honestly wondering since I have no feelings for any company even if their products are amazing.
I've been a fan for much the same time period yet never owned an AMD powered device, except maybe a game console? AMD has been useful to keep Intel on top of their game, but Intel has been on top for most of the last 15 years give or take.
It was really about them being an underdog, more than anything. Challenging the big dog and occasionally forcing them into more consumer-friendly behaviors.
That said, I still ended up owning mostly Intel CPUs (a lapped Celeron 300a running at ~514mhz in the K6 days).
