I teach English in Mexico City. Having to lug my laptop to and fro isn't the safest of situations. I now put my PDFs and DOCs in a folder, my MP3 and MP4s in a folder. Hook up the phone to a LCD tv or a projector and I can do what I was doing on my laptop before.

I also use the DICT programs and display the various dictionaries to the class. I can zoom the document pages with ease.

Every student has asked me where they can buy one. Sadly, the 'newest' thing from Nokia here is the horrid N97.
