Best expierence, when I got my Storm on launch day they said they only had 4 and I was 6th in line. I resigned myself to accepting 2 day shipping, but guy 5 decided to try another store, RIGHT after he left they found a 5th Storm, and GUESS WHO GOT IT!!!!! The manager said to me "..ding ding DING, you're getting a Storm!"
i've only had my berry for a little over a month as of now (knock on would) i have no "worst experiences" yet...i guess i'd have to say my best experience was seeing that fedex box in my mail last month!
