We are getting closer to Angela Ahrendts' start date at Apple (this Spring) and MacRumors has posted this nice overview of how she will fit in at Apple, and more importantly what she brings to the table.
I'm very excited about this hire and think Ahrendts has a lot to offer. I expect her style, coupled with iBeacon technology, to completely reshape the retail experience and give the whole thing more of a 'premium brand' feel.
