I have done an analysis of SIRI and XMSR (mostly SIRI so far) and although they have reached a large market and can arguably obtain many more customers, both of their F/S look dismal. Both cannot sustain themselves without the finance of shareholders. Especially, SIRI... Shareholders Equity has been cut in half in the last 12 months and they continue to borrow large amounts to keep a positive cash flow. My personal opinion is that they are both in too far over their heads. It is just a matter of time until they collapse. -R.T. I have in-depth analysis available if you want to see it.
