Yes, you got that about right. The two Steves came up with amazing things in their garden shed.
How many amazing things have Apple come up with in recent years(!)?
Where's the innovation? Where's the cutting edge?
But if it takes this megalomaniac building to get them to that point then it's all good.
*sigh*
With all due respect to the Steves...
Back when they were a teeny company, their most exciting products were a bulky PDA that never took off, a bulky original iPod (gimped by only working with Mac), & a bulky Bondi Blue iMac.
Their new industry 1st 5K computer (the new iMac) at a price the other guys are charging just for the display, their impossibly teeny Mac Pro, the very light & capable iPad Air w/ TouchID, & hotcake outselling iPhones are to me much, much, much more compelling than their original products.
It's like tech finally caught up with their imaginations! I feel like they're only just now creating the devices & services they've had in mind for many years.
Now, a large part of why they can create such products is because unlike Samsung, for example... where their components division is so separated from their mobile division that neither is allowed to let the other know what they're working on, or cut a good deal for them... at Apple, Jony has his design & engineering teams sharing the same vision and daily work space. This cylindrical building was created to foster this innovative spirit.
I'm sorry that you lack the imagination to see it as more than a "megalomaniacal", ego driven project.
That's an absurd opinion to me... but, to each their own.
