Every now and then, I find a digital marble which seems to make my PDA and mobile phone twice as useful as before. Wapedia, a service of Florian Amrhein, is my recent discovery. The website offers an interface to the Wikipedia database for (wireless) devices with small displays. The result of a query is reformatted for small screens and pictures are reduced in size for quicker download times and better viewing on a small device. Answers to questions such as "Where is Austerlitz?" or "What is a Home Agent?" at the breakfast table or while sitting in my favorite cafe in Paris or in a train are now only a couple of clicks away. Great, thanks very much, Florian!!!
