I was at a conference last week where members of the media were given free 2GB iPod Nanos. White. A wonderful gift, but I already have been using a 5GB Zen Micro for near a year. Black.
By default, my youngest daughter inhereted the Nano, since the two older siblings weren't interested in it. I found her a trial copy of Anapod Explorer so that she wouldn't have to install iMusic on her PC.
Over the last few years, I've received some very nice gifts from corporations. The drawback is that the free object results in an expense for me. The GPS unit? I bought some data and power cables for its proprietary connector. But I find I never use the GPS. The wireless iPac? I bought a larger battery and SD memory card. But I found I didn't like the Windows OS, prefering my PalmOS device. Same for the Nano: I prefer my Creative Zen Micro, which has larger capacity, replaceable batteries (I have 3), and built-in FM radio and microphone.
The Nano is sexy. Mobilemag reports that Apple has sold 14 million iPods during the last three months of last year. By comparison, Creative sold "just" 2.6 million of its MP3 players.
