The air comes no where even close to the mini for portability. Its much heavier and about 40% larger. The mini is the best on the go tablet. The air is more for in the house or office. Its just not practical like the mini is. Thats why the mini outsold the 4th gen ipad in the past year, cause people want more portability. I cant even remember the last time ive seen someone in public lugging around a full sized ipad. Most leave them at home cause theyre just too cumbersome. Its like lugging around a solid marble tile.
I cant believe that ipad mini original outsold the ipad 4 retina? no way! Source?
