Top 10 PDAs

New Windows Mobile models dominate our Top 10 PDAs chart this month. A few--including units from HP and Asus--have both Bluetooth and Wi-Fi connectivity: By adding a Bluetooth cell phone, you can send and receive e-mail or surf the Web from almost anywhere. A couple of interesting units don't appear: Mitac's Mio 168 GPS, a Windows Mobile PDA with a built-in GPS receiver, was expensive and hard to use, so it missed our chart; Dell's Axim X30--the successor to the Axim 3i, our last Best Buy--hadn't been released at press time. Look for a review of it in next month's New Products.
