"For about the price of one CD, Napster subscribers can now pack their portable music player with unlimited songs, delivering a new challenge to Apple Computer's buck-a-song iTunes model. Napster To Go launches Thursday and costs $15 a month. It's the first digital music service to use Microsoft's long-anticipated Janus technology, which allows monthly subscribers to take their music with them instead of having to pay for an individual song each time they want something new in their MP3 player."I think this sounds like a really nice idea that I would like to try out -- if this were to be available in my country. How many of you have tried out Napster To Go? Do you think it works well? Is this a serious contender to iTunes in your mind?
