Youngsters might not remember, but I've followed those keynotes and introductions since 2002 or so.
It took 4 years for the iPod to get a color screen -- and 8 years to get a video camera. Several years to get Wifi. The original iPhone wasn't 3G -- that was the next model. Those years we waited year over year for Jobs to announce some extremely incremental updates. And people cheered for them -- they were actually exciting, all the press was speculating and gushing, and it was e.g. just a few additional features on the iPod, like the touch wheel as opposed to the old click wheel.
New announcements like the iPhone and the iPad were rare under Jobs too. And those products were low hanging fruit for Apple themselves -- a mobile phone and a table. Quite basic stuff -- not some whole new product category like flying cars and whatever people expect to see.
Apple is not in the business of creating experimental stuff to dazzle geeks. It's in the business in incrementally improving mass market products.
Besides, what competitor exactly did introduce those mythical "Jobs-worthy" products that people ask from Apple to deliver? Google Glasses? Microsoft's laptop/tablet combo that failed to gain much traction and is returned like crazy? https://www.theverge.com/2017/8/14/16142490/microsoft-surfac...
What Apple did better, and affected the industry, was not innovation in the sense of some new BS product category that didn't exist ever, it was delivery. Better thought out, more polished, and with lots of innovation in the details. The kind of innovation that the iPhone models get incrementally but few can understand, but then you use a model from 2-3 years ago and it feels ancient after you've used the last one.
For such introductions of new products, the Apple Watch has been one such under Tim's, err, watch, and it does great in the market (in fact it's almost the only smartwatch people can actually see in the wild -- it outsold Samsung Galaxy watches so much in units it's not even funny).
