Why would Apple choose the company that has roughly 1/8th the subscribers of the other 350,000(sirius) vs 2,000,000(xm). Where is the business sense in that? and the more expensive service to boot? $12.95 vs $9.95? unless the portables have some mega amplified antenna theres no way they could work indoors... with my skifi radio, just going through one wall knocks the signal down to 50%
It seems to me there are way to many cons for the pros of this to outweigh. Would you really want your ipod skipping if you went next to a tall building? Seems to go against that whole "ease of use" thing apple is going for.
