For those who need a PDA with the power of GPS, as opposed to some of the PDAs on the market with half hearted GPS efforts, one could do a lot worse than Asus' MyPal A636. Itís a full Windows Mobile 5.0 device with Bluetooth, Wi-Fi and a fold-out 5 x 5cm GPS antenna. It also boasts a 3.5in, 240 x 320, 65,536-colour LCD, 802.11b Wi-Fi for broadband links and Asus' own Wi-Fi Manager utility, which you can use to scan for hotspots.
