My wife has had XM for about a year now and she has me completely hooked. At first, there were a few things I didn't like about the service but it seems like they have really improved things (commercial free) and I'm ready to take the plunge for myself. The difference with me is I want to use it only in my office. I work in New York City and take the train to work every day so I am looking to buy either the Skyfi or the Roady to hook up at my desk and possibly at home for the weekends. The big question is, does it work if I'm not near a window? I work in a closed room with no windows and it's near a data center so is there any possible way I can get a signal in there? I figured I may have some luck being in New York and possible being close to an antenna. My building is one 26th street between 11th and the West Side Highway so it's not like I'm in the congested building area of Midtown if that matters at all. If this is at all possible, I will go out tomorrow and buy it....crosses fingers.
