Sirius has a portable device (S50), and although it is very sleek, it is kind of difficult to navigate. I'm looking for a portable device, since I'll be using it at work, primarily. XM's service comes with online streaming, same as Sirius. Sirius's salsa station has salsa, merengue, etc etc. bunch of crap i really have no need to listen to. XM's has purely salsa, which I like. It's music that isn't readily available where i live. I'm also a big fan of talk radio (NPR, Public Radio), and both companies carry very similar choices. I think the maker/breaker will be MLB, since I really don't care for NFL, Nascar and the rest.

I heard Sirius is having their fair share of cash flow problems as well. take a look at their stock compared to XM. 12 bucks per share XM and 4 bucks for Sirius.

I get a discount for Sirius at work, though. I'd be lying if I said that didn't come into play. We'll see what happens.
