I've had XM on my PC before but it was only the music channels. It wasn't the talk radio, or sports, or anything that I really wanted. So it wasn't worthwhile to me. I hope a BB version carries the talk/news channels.
I had a trial version some time ago for XM on my old 8830WE. You could stream XM. I didn't keep it because I have Sirius. I wish I could remember where I got that from. It worked pretty good. Although like most of those streaming apps, it can put some mean hurting on a battery.
