I guess it's because of many reasons. Why sell something that is very outdated for being a tablet...Why pay $400 for something that is 3 years old. Running a heavy os with limited ram. Also the iPhone 4S will be replaced tomorrow with the iPhone 5C 8GB. It makes NO sense to be selling A5 hardware now because think about it...If they are STILL selling it for so long it would have to also run iOS 8 and maybe iOS 9. It's a huge mistake. The jump from the iPad 2 to iPad Air is huge when it comes to the screen and processor.
