I remember installing the OS X Developer Preview 3 on my bondi blue iBook when I was in high school. Worked at a movie theater over the summer, and saved up enough money to get the iBook - first computer that was every truly "mine." I think I was a member of the Apple Developer Program for Students - because I remember being shipped the CD for free...but I could be wrong, it was a long time ago. In any case, as cool as the DP3 looked (at the time), and as neat as some of the features were (I especially loved the Dock magnification), it was buggy and slow! But honestly, it didn't matter. I had grown up using Macs, even had a subscription to Macworld, and I knew how dire things were for Apple. As good as Classic Mac OS had become, it was still drastically limited compared to Linux and even Windows at that point - OS X was the future, and there was so much potential in that DP3. By the time the Public Beta was released, I was in my freshman year of college - my family came together and bought me a gorgeous PowerMac G4 for H.S. graduation, and I set up a duel boot system so I could run Mac OS 9 and OS X together - as Classic in the Public Beta wasn't great (nor was the Public Beta for that matter). I miss those days sometimes, computer weren't as streamlined yet, OS X was a gorgeous mess, and Mac OS 9 was like the little OS that could - considering it's limitation it's amazing how far Classic Mac OS brought us.
But I digress...
I know there are a LOT of opinions on these forums about Forstall, and Cook, and of course Jobs - but perhaps, just for a moment, we can all take a step back and appreciate how far Apple has come since OS X came out. Even after Jobs came back, even after OS X was officially released, Apple was not in a good place...and now, they're the first company to be valued at a trillion dollars. Some may not like the decisions Apple has been making these past few years, put dammit if Apple isn't still Apple. Look through all the screen shots, yes the look and feels has changed, things have become "flatter" and more streamlined (I personally like it, but I respect those who don't), but the core is still there - macOS is still fundamentally OS X, which owes a lot to Classic Mac OS - Apple is still Apple...and I'll never stop being a fan.
