I still have my old Sony first gen radio with the gray scale screen (alhough it's not activated anymore). The little bugger worked well but was rather cumbersome. The MyFi I have is working great (knock on wood). I have it set up at home and connected to my Cambridge Soundworks radio. It really sounds good. I also love the fact that it has an alarm. The XMp3 doesn't have an alarm, does it? I wish the Inno did also. Also, even though it is much bigger than my Inno, the pre-set buttons on the front of the MyFi are very convenient. And there are lots of them, 30 if I recall correctly. I don't see much in the XMp3 that is so new that I need one to replace or supplement my Inno or MyFi.
