This is weird topic, but I'll address the poorly written article.
1. Unix — This isn't true. Avie Tevanian is the reason Mac OS X was based on Unix. He created the Mach kernel (in college) and was the Senior Vice President of Software Engineering at NeXT, then at Apple until 2003 or so. He was responsible for both Mac OS 8.5, Mac OS 9 and the first three or four version of Mac OS X including the expansion of command line tools.
You can listen to the entire story here:
2. Leopard — Leopard development was pretty much a disaster. It's the only Mac OS X release (other than the original) that was demoed at two simultaneous WWDC because they couldn't get it done. Forstall pulled resources from Leopard to finish the iPhone OS. Additionally, Leopard was considered buggy, shipped with missing features including features that were shown off during both keynotes (such as "Stacks", iChat hologram effects, AirPort Extreme's ability to serve as a Time Machine server and more).
Bertrand Serlet had to come in and fix the bugs in Leopard, which is why Snow Leopard was released.
3. Aqua User Interface — Forstall was the lead designer on the Aqua User Interface. His work on Aqua is what elevated him at Apple. However, he's never taken credit for the "lickable" interface that I'm aware of.
4. A Touch-First Operating System — Apple had been working on a tablet prior to iPhone. Forstall gets credit for creating the first iPhone operating system team and shrinking Mac OS X down to fit on a phone, but there were a lot of bright engineers taken from other divisions that deserve just as much credit.
5. Android — This topic makes no sense. Forstall didn't have anything to do with Android.
Bottom line, if Steve Jobs thought Scott Forstall should be the next CEO, he would have elevated him before he died. He obviously didn't think Forstall was ready or capable. Also, Steve Jobs would have never picked Forstall over Jony Ive and that was the rumored clash.
Judging by recent interviews from him, he sounds like he's happy producing Broadway shows and living the good life. He's never once spoken out against his firing or Tim Cook.
Why are you bringing him up now?
