PC World checked out the quite expensive MyPal A730W PDA from Asus. Here's a snippet from their review:

Asus's $559 MyPal A730W adds built-in 802.11b wireless support to the remarkably full-featured MyPal A730 that appeared on our December 2004 chart. However, all of its extras--such as two expansion slots, two batteries, and a large screen--come at a cost. For the price, I'd like to see better battery life and a more solidly built case.
