Obviously you don't know what you're researching. Siri-XM is a Radio station company. Who tramsits their radio info over satellite. IRDM is a satellite communications company that allows people to use thier technology to communicate all over the planet from remote/nonremote locations via their own satellites. NO they are different. Siri-XM is barely making money, where IRDM has contracts with the gov't (US) and other well known companies. SIRI-XM says a subscriber is anyone/thing with access to the radio, IRDM's subscribers are those using the product. Just a couple BIG differences. IRDM's growth will increase over time as the need and technologies chnage in the communications space, SIRI-XM is a declining fad, that will one day probably lose the Satellites and go straight throw the internet or fail all-together! BUY IRDM!
Wow,you are wrong in a lot of areas,sirius subscibers pay a monthly fee and use a digital sirius radio.they just doubled their profits.ive never ever heard anyone say they will ditch the sattelites.jus sayin
