I could not care less about Samsung. I know that while I am typing on my iPhone 6+ while it rests on a table, it is wobbling left and right.I would much prefer to have extra battery filling the space stupidly saved for fake thinness.
My 67 year old mom, 40 year old wife, and 5 year old daughter all use iPads exclusively. Mom never used computers before. Wife switched from PC and never looked back. True they are not power users, don't create content, but there are many more consumers than creators, and iPad perfectly addresses that market. So your single opinion is not representative.
