This is the device I’ve got my eyes on:
I seriously considered the Treo 600, but got scared off by the 160×160 screen and the apparent lack of quality control, that I deduced by reading about repeated problems at the [TreoCentral forums][]. Now that there are rumors that a Treo 650 for Cingular is coming soon, I may have to give the Treos another look.
