They may not be selling many Blackberries, but they seem to be doing OK in real-estate. They just sold five buildings to the University of Waterloo: http://www.theglobeandmail.com/report-on-business/university-of-waterloo-buys-blackberry-buildings-land-for-41-million/article16074015/

I use a Thinkpad with Camtasia to record the audio of the lecture and do screen capture of the PowerPoint slides that are provided by the prof. I also edit the slides on-the-fly to emphasize important points. This allows me to listen & view the lectures repeatedly when necessary. Occasionally, profs will omit diagrams from the slides... yep, then I use pen and paper. I use an Ipad to reference the textbook during the lecture and to look up terms that I am unfamiliar with. Works for me... -Cos.
