On stage at Macworld 2011, two of our friends from iFixit, Kyle Weins and Luke Soules, attempted to fix broken Apple stuff right in front of an audience. The session was moderated by Chris Breen, who asked the audience to bring up their broken gear in the hope that it could be fixed right on the spot.
iFixit, for those that don't know, is a firm that not only posts teardowns of popular Apple products, but strongly believes in empowering users with the ability to fix their own Apple equipment, and sells replacement parts and tool kits to allow people to do it. As Luke attempted repairs, Kyle described exactly what was going on. Unfortunately, they weren't successful at any repairs during the session, but they were working under some impossible conditions. People in the audience had a lot of different broken things, and iFixit was only able to bring in two boxes of parts, which limited them dramatically.
