Continuing our look at some of the more interesting devices and services we ran across at Macworld
in San Francisco last month, MacNN and Electronista staffers will periodically write about items and vendors that caught our eye at the show that we thought our readers would like to know about, particularly as they start accepting pre-orders. This week, we check out the Hidden
Bluetooth portable speaker, and the new Prong PWR case
for the iPhone 5 and 5s.
