You can now get this little gadget for less than $150 (you can get it here, for example). WiFi enabled, allows you to listen to net radio, integration with Yahoo Music Unlimited, which means you can now download tracks straight from Yahoo Music if you have a premium account. Get one of these and sign up for the service via this promotion and you get 2 years of unlimited portable music for less than what you pay for an iPod.
2 years of unlimited music on the go for $300. That’s less than $0.50/day. Definitely sounds better than getting an iPod, where owning the device itself will cost you the same amount.
