My kids, for example....
I got each of them a Huawei Sensa phone for about $25. Has a better camera than a typical tablet, can be hooked up with Google Voice to act as a free phone, text, etc, etc, etc, They each also have an amazon tablet. Guess what they play with? The phone. When the phone gets to more than 5.5" 1080p screen with memory, it suddenly has a higher appeal than a tablet.
