- iPad has established a new category of tablets computers.
- iPhone has established a new category of mobile phones.
- iPod has established a new category of music mp3 players.
- iMac has established a new category of all-in-one desktop computers.
- Macbook air has established a new category of thin, full keyboard and disc-less laptops.
These are categories that hardly existed before Apple built them. Of course all these categories were created under steve jobs even Apple Watch was conceptualized under jobs now what we are eager to see is for tim cook to create a new category. One more thing a category does not mean an invention of new product rather then transforming it and making it a trend even iconic and of course easy to the extent that people start using the product name to mention a category. Like Kleenex for tissues, iPod for mp3 players and iPads for tablets.
You are incorrect.
iPhone wasn't the first smart phone. IBM has developed a smart phone well ahead of Apple. Palm Treo was also another immensely popular smart phone. Also predating the iPhone. Apple again watched, learned, and launched the best smart phone at the time cornering the market.
iPod wasn't the first MP3 player. Diamond Rio was one of the first successful MP3 players. I even had one! Apple saw an opportunity and a pain point (small capacity) and develop the world's first hard drive based player that changed everything and revolutionized the industry.
iMac wasn't the first all-in-one desktop developed. That title goes to HP and well before Apple.
MacBook Air isn't an invention. It's a laptop that happens to be thin, but Apple didn't establish the category. I believe the first Ultrabook (which is what MacBook Air is essentially) was developed by Intel. Acer and Lenovo both had an Ultrabook well ahead of Apple.
Apple is a close follower and a darn good one.
