I like the Pixi! So yeah, it is low end compared to the Pre with its 2MP Camera (fine by me), slightly smaller screen (WebOS scales everything anyway - practically a non issue), no WiFi (I practically never use the WiFi on my G1) and slightly slower processor (ok thats annoying).

But, its really slim! Very pocketable, no sliding and moving bits is a huge bonus and supposed to be cheap too. I like it a lot, its like a WebOS Treo.
