I had a Sidekick B&W in high school, and later a Sidekick Color, and people would ask me about it every single day. I remember having long AIM conversations under my desk in class. I later upgraded to a Sidekick 2, which was nice but had some build quality issues. I must have gone through at least four of them. To T-Mobile's credit, they were very good at replacing them quickly. I remember sitting at dinner one night, flipping it open to answer an IM, and the screen detached and flew across the restaurant. I replied that my screen flew off and that I would have to respond later :)
