Not to mention media-centric phones without headphone jacks. Remember how services like Apple Music are supposed to be the company's future? Hey, let's make it HARDER for users to consume those services, by removing the audio output and battery life! COURAGE!
As for the headphone jack, if you think it was a stupid idea to remove it, you should save your vitriol for the "idiots" who copied Apple. Surely it's worse to take what you'd class as an obviously stupid idea and blindly copy it like a brain-dead zombie. At least what Apple did showed actual courage. And yes, I'm using that word entirely un-ironically. I personally think it was courage and they've been proven correct by the rest of the industry.
(Personally I'm glad they got rid of the headphone jack because it prompted me to get a pair of Bose QC35 headphones. Absolutely brilliant. Best headphones I've ever owned, and I've owned some high end ones. Meh. I'll leave the "good sound" at home thanks—when I'm out and about I care far more about blocking out the distractions than maximal audiophool wankery.)
The G3 cube was a good idea but was overpriced, as it was inferior to the regular G4 in every aspect other than size. It was priced to be a 2000’s-era executive desk ornament, a relatively tiny market segment. A few years later a substantially similar product was released to massive success—the Mac mini.
The puck mouse was stupid, but it wasn’t as bad as people made it out to be. It was eminently useable once you got used to it.
Jobs’ biggest design failure has always been his refusal to acknowledge the importance of cable strain relief.
Also the third generation iPod. Yeesh.
