Well, unless you plan on buying a new one every year and a half, I think it's a bad idea. They may have good customer service, but you'll pay more than it's worth in the long run. Here is why I think it's a bad idea:
Battery life of less than 10 hours
malarkeyty sound (yes, malarkeyty sound.. I have $120 headphones and no matter what setting I had it on, it always sounded strung out)
Costs too much
I own one, and I still don't like it. It crashes on me all the time now, and the way you update your songs is a pain to me. If you want to delete songs, you have to delete them off the playlist on your computer, and then re-update the whole thing.
All in all, it looks sexy, but is a poor lay.
