I am always impressed when I have to go to the Apple Store to have something fixed under warranty (i.e. I don't have to spend moola!).
My earbud busted this morning. I went to the Apple Store to get it fixed. This is the second time I've gone because of a busted earbud. This is the second time that I had someone look at it in under 10 minutes, ask me what was wrong and hand me a new pair of earbuds.
No hassles. So impressed.
