Along with the Palm Z22, Palm also announced the Palm TX officially.

Palm positions the Palm TX as a low-cost WiFi enabled PDA. Palm TX also features Bluetooth to connect via a mobile phone to the Internet on the go.
The Palm TX sells for $299 at the Palm Online Store.

The Palm TX is less powerful than Palm Tungsten T5. Palm lowered the price for the Palm T5 a bit to $349.
Both, the Z22 and the TX are entry-level models, but then how much PDA power do you really need. Palm TX Main Features:
