This move seems to be geared towards keeping up Apple's image as much as convenience for those that live in SF. The only convenience I can image is for those at Apple that setup the annual SF events like WWDC, and others.
Frankly I seriously doubt that there's many Apple employees that actually live in one of the most expensive, small, heavily crowded, major metro cities in all of the USA. Once a resident myself, right out of college, I enjoyed SF prior to the high tech invasion which drove the already high prices to astronomical highs that are causing major issues today.
With it's astronomical real estate prices for eighty to one hundred year old homes, the few people I know that grew up in SF, fled (like I did) to the peninsula as adults where for the same amount or less they could have three times the square footage, a far newer if not brand new home with ample parking, and still have the high end image.
It will be interesting if Apple keeps it's operations there secret, or mentions just what departments they have moved there. I'd venture a guess if they comment it will be one of their carefully crafted statements just to get the press off their back. In many ways it's a surprise that they failed to do this before the ultra staggering lease factors hit.
The Peninsula is suburbia. I wouldn't live there. Parking? Who cares? You don't need to own a car when you live in a real city (note: I live in NYC). There's also a reason 80 to 100 yr old homes sell for those prices They are often bigger, better constructed, have character, and more details that slap together cheaply constructed new properties don't have. People like to buy these old classic homes with character and restore them. One of my friends has done just such a thing with a home nearly 100 years old. You know the saying, "They just don't build 'em like they used to". Sounds like city urban life isn't for you. You also seem to be preoccupied with "image". Move to Walnut Creek?
