The good news: when I called Apple support to report a dead ATI Radeon 2600 XT, they arranged to have a replacement one ready for me to swap at the famous 24-hour Fifth Avenue Apple Store. No hassles whatsoever.
The bad news: when I left the store with the new graphics card in my hands, I had a $115 parking ticket waiting for me, on top of the $25 I’d just spent on a Zipcar to get down there. The moral: Apple good, taking the subway to Apple Store even better.
