Funny thing about Wikipedia, the Internet's giant user-created encyclopedia. it's so small. It seems to contain summaries of all the world's knowledge. Yet it really takes up remarkably little space in digital terms--about six gigabytes. Heck, you can fit that much data on a smartphone these days.
And here's an app to let you do it. AllOfWiki Offline is a $10 app for iPhones and iPads that does something very simple and powerful. It downloads all the text content of Wikipedia, and stores it in your device's memory. Now it doesn't matter if you can't score a Wi-Fi or 3G connection. You've always got Wikipedia, as well as an nice-looking interface for quickly looking up information on pretty much anything.
On the downside, updates--available on a monthly basis--are $1 apiece. If you're a hardcore user you'll probably want those updates, and so the price of the app soon gets a bit steep. And with Wi-Fi connections so widely available--Starbucks Wi-Fi service goes free-of-charge starting next month, this is an app you can easily live without.
Still, it's kind of cool to tote around this much knowledge in your pocket.
