WikiReader, the offline wikipedia gadget
Found this interesting gadget in Taiwan. The WikiReader lets you carry offline Wikipedia in your pocket. I find it useful while researching something on the plane. A recent archive of Wikipedia is stored in a SD card that is slotted inside the WikiReader. We can download the latest archive and update the WikiReader.
I like the Random button. It takes you down a rabbit-hole of random trivia.
The WikiReader is often a conversation starter in planes.
