If you want remote access to Wikipedia but don't want to shell out for Amazon's Kindle, consider downloading Pocket Wikipedia 1.0.

Here's how Free Soft describes it:

"Pocket Wikipedia, hand-checked selection from Wikipedia which is about the size of a fifteen volume encyclopaedia (24,000 images and 14 million words)

The selection was made by Schools Wikipedia...This application it's a freeware software, works on PocketPC, Windows and Linux."

The version is static and does not update. But, it does contain a massive amount of free information. Plus, you'll have a greater assurance of quality content since everything included has been double-checked.
