(Incidentally, is there some trick to making Wikipedia work on the Treo? The pages are readable before they finish loading, but then they blow up: most of the text vanishes, except for some gigantic-font headlines.)

Update: There are several sites that provide PDA-oriented copies of Wikipedia, and pda.en.wapedia.org seems to be the best of a bad bunch. Most of them strip out all of the images; wapedia.org tries to include the images, but screws up on half of them.
