usually under the tech-spec from apple.com, the wifi version and cellular version iPad have two sets of different pictures, with the plastic antenna window on the cellular version but just took a look at the tech spec on both iPad pro and iPad mini 4, both have only 1 set of pictures. at first i thought it was because neither of those are 'released' yet (admit it, iPad mini 4 is not released until iOS 9 is), so apple just put two versions together. but then, i found that, the weight for two versions are still different, plus under 'power' section, the battery life is also different for the two versions. so, does this mean that we no longer have the ugly antenna cut-out on cellular version? any thought?
