Apple iPad mini with Retina Display Reviewed

Battery technology is improving.

"The Retina mini now features a 44% larger battery (23.8Wh). That’s nearly the same battery capacity as the original iPad (25Wh), but in a chassis with only 1/3 of the volume. This is also the highest capacity battery we’ve ever seen in a tablet of this size. The negligible impact on weight and thickness is pretty impressive"

Wonder if this battery technology will find its way into the next Telsa.
