Apple is periodically a boring company. It just made better macs for a decade, and slid into irrelevance. Then they got (back) a CEO that made their products relevant again. Then he died. So I'm predicting history will repeat itself.
That's not really a fair characterization. 1990s Apple did indeed only iterate its Macs until Jobs returned, but they absolutely didn't stop trying to innovate – they just didn't do it with focus. I mean, Apple invented the PDA without its co-founder at the helm, and repeatedly tried to put a revolutionary operating system on the Mac, but failed due to institutional bloat and uncertain leadership.
