"Charge your iPhone and battery case simultaneously for increased talk time up to 25 hours, Internet use up to 18 hours on LTE, and even longer audio and video playback."
Wow! I think I should be saying wow. Right? While it's not the newest, cheapest, or most powerful battery case on the market, as Fortune points out, the Smart Battery case is retailing at a competitive price point, as Mophie's 2750 mAH Juice Pack Air sells for $99.95.
In any case (get it?), it's a pretty cool thing, and probably even a great Christmas/Hanukkah gift (shalom!), but not everybody is so pumped about the new product -- specifically, design geeks.
