Apple have never really invented much. But, they have brought together technology and made it into amazing things.
The imac. It was colourful, compact, got rid of legacy ports. It was insanely great. The iPod put a Hard drive in a MP3 player, and made it easy to hold your entire music collection.... The others on the market just were shite in comparison. This was insanely great. OSX, bringing together open source Unix, with a Java JVM installed as standard, using open API's and with a GUI that was far ahead of anything at the time...... Insanely great.
Soldered in Ram - not insanely great. Non upgradeable SSD - not insanely great. no USB ports on latest macbook, and charging premium for a USB-c adapter. not insanely great. Charging $1,099 for a 2012 model laptop with 4gb ram and crappy i5-3210M processor......FFS, not insanely great.. For heaven sake, I remember Steve jobs reducing prices of models every single mac world presentation. No more.... Not insanely great.
Apple are dead. Maybe not in the financial sense - they have enough money to keep them going for decades. But, in the sense of what brought them back from the brink of bankruptcy back in 1998, they are dead and buried. I only wish Microsoft were a better company so I could switch back.
