Let's be honest, it's not minor.
You could have an amazing dining table, polished walnut wood with mahogany inlays, gold metalwork around the legs, all beautifully french polished.
They remove half an inch off one of the legs, so whilst everyone is sitting at the table eating their meal on fine china, the table keeps rocking every time anyone places any weight on the table.
Lovely table, but the experience is ruined.
Holding the table up the wobble is gone.
So Apple would make an anti-wobble case for the times you want to use your phone on a flat surface?
No, this is nothing like your example. That would be like you using your phone in your HAND and it wobbling and doing something to ruin your experience. A table is meant to be used as such, and yes a short leg would ruin the experience for the table, but to say a phone which is used primarily in your hand would have its experienced ruined because of a small protrusion on the back is a stretch to say the least. I have an iPhone 5S and an iPod touch with the protruded camera. Using it on the table is not affected by its camera, nor does it ruin the experience. While we are at it we might as well say the rounded edges would ruin the experience of the iPhone 6 because you couldn't place it flat on its side while watching videos or recording! The experience is ruined!!! (sarcasm)
