Put bluntly: this is bullshit. The advance notice was slightly better than last year, but the website was intermittently down for the entire two minutes tickets were on sale.
I was there, trying to buy them at 9:59am, at 10:00:20am the website finally went live, pressed the buy button and was greeted by "unable to process your request."
Seriously, Apple needs to figure this shit out. Whether that means opening up more seats, making tickets more expensive, or even just having a website that doesn't go down on you… something.
