Feedback on Palm OS 5 PDAs?

Dark Neuron asks: "I work with a PDA software development group, and have been interested in the changes in the Palm Operating System (from 4.01 to 5.0). There are 2 new devices available, the Sony Clie PEG-NX70V and the Palm Tungsten T. The Tungsten has built in Bluetooth, and the Clie has the advantage of an accessory Wireless LAN (WiFi) card. There are some Secure Digital 802.11b cards in development, that could be used by the Tungsten (the power drain of which I do not know) but none available yet but they may be out by 2003. Does anyone have experience with either new device yet, or knowledge of Secure Didital WiFi cards in development? Any feedback on the New OS 5.0 yet?"
