Wifi USB flash drive

So I listen to alot of music on my pioneer avhx-2500bt via bluetooth. I'm using my Galaxy S2, streaming Pandora, downloaded music on my phone etc..

I've just started using the 32gb wifi flash drive that I find incredibly awesome. Basically I send files to my flash drive that stays in my truck. It has its own secured SSID which i've renamed. I send music, videos and pics to play. Jump into the truck and jam on!!

There is an app for it as well.

Is there any other uses for this neat device?
Use it as a wifi extender? Wireless bridge?

Thanks,

I like it! I might just ask the wife for one as a stocking stuffer!

 

Winning. I assume it has to have power 24/7 to be able to broadcast, how does that affect your battery?

Edit: Provides up to four hours of wireless streaming per charge1
1 Based on streaming 720p content at 2Mbps to one device; actual life and performance may vary depending upon usage and settings; battery not replaceable.

 

I had no idea this thing existed. I don't know what else it can do but from the description, I may need one or two or 3.
