I am thinking of going with satellite radio, but I want to get it across all of my devices.

I know the difference in the companies as far as service offerings, but which is better on the Treo? I know Sirius has SiriuCE and XM has the website where you can stream XM onto the Treo.

Can anyone tell me - is there a quality difference in using SiriuCE or XM on the Treo? I know the website said XM only comes in 64K off the streaming website. Does SiriuCE offer higher fidelity?

Thanks for everyone's input.
