Agree completely: Apple stores used to be places where you could expect to be treated as if you had real value. My time in them goes all the way back to the PPC days (yeah, I had one of those dome iMacs and thought it was the most brilliant design ever). Whenever I had a question or problem, I could go to the store confident about how I'd be treated there. They would sooner freely replace a device than see you walk out unhappy with the visit (it happened for me once, with an early MacBook Pro -- they spent an hour working on it and finally made some phone calls, got approval, and sent me home with a newer machine and a promise to get my data preserved from the old one onto an external drive, a promise they fulfilled).
Now? They're just another over-large, profit-obsessed corporation that does assembly-line customer service.
In a few different studies, researchers at Loughborough University in the UK found that when tired participants took a 15-minute coffee nap, they went on to commit fewer errors in a driving simulator than when they were given only coffee, or only took a nap (or were given a decaf placebo). This was true even if they had trouble falling asleep, and just laid in bed half-asleep during the 15 minutes.
New book about an author with a similar perspective: Decker's bio of Hermann Hesse, just published by Harvard U. Press. If like me you grew up reading Steppenwolf and Siddhartha and Demian and Magister Ludi, this bio may have some meaning for you.
No amount of genius can overcome a preoccupation with detail.
