When I first checked out the first generation of XM2go products from Pioneer, Delphi, and Tao, I had to scratch my head. Though they were cool because you could suddenly take satellite radio with you wherever you go, I remember walking around with one of those enormous beasts in my hand thinking how nice it would be if the device were smaller and could hold some of my own music as well as XM content. Sure enough, the new Pioneer Inno ($399 list) is better in just about every way than its predecessor. The player's integration with the XM + Napster client takes a cue from Apple—imagine that, hardware and software that work really well together! (The Pioneer Inno and the Samsung Helix have the exact same interface and nearly identical hardware.)
