I use Wikipedia quite often to get quick info on a variety of subjects throughout the day. Sometimes the connection speeds can be slow or disrupted due to weather or peak hour internet use. Wiki Offline is quick , so quick , that I am still focussed when the page pops up and I can learn more, faster, anywhere. The bookmarks can be customized and the interface here is simple, friendly and useable. It takes 3.5 GB space on the hard disk but this is the human body of knowledge at your fingertips and is well worth 10 bucks.
