For $10, I'd use it as an MP3 player at the gym or when out walking... so I don't have to worry about dropping my expensive phone (as I'm prone to do once a month or so). 4 GB would hold more Spotify playlists than I would ever need at one time.

It's amazing that as recently as five years ago, I was paying around $100 for a dedicated MP3 player for exactly this purpose.

I'd have no interest in the "phone" feature... and would never even install a SIM card. I have to believe that many people have thought of this idea, and that has to be a problem for TracPhone since they're probably selling this device at a loss in order to sell phone/data services.

So since it's "Out of Stock" right now, I wonder how many ever were in stock in the first place? My suspicion is that they released a small number of devices as a P.R. stunt to attract publicity. The hope being that some number of people who click the link to check it out will proceed onward to buy one of the "real" devices that isn't being sold at a loss. I'd be surprised if you ever do see this $10 model "In Stock".
