By the way I can't agree with you on iOS from my personal experience. If you are using the phone as a phone it works very nicely. Admittedly it's not great if you want to write code or some such but there are other devices for that.
I'm not sure that's true though? They did quite alright over the next ~5 years or so and the way how Jobs handled the Lisa or even the Mac was far from ideal. The late 90s Jobs was a very different person from the mid-early 80s one.
IMHO removing Jobs was probably one of the best thing that happened to Apple (from a long-term perspective). Mainly because when he came back he was a much more experienced capable person and he would've probably achieved way less had he stayed at Apple after 1985.
