it is made of colorful plastic,we can only judge it for what it is,not what it could have been.(ex if it was not made of plastic / if better colors were chosen)
5c is probably the ugliest Apple product ever made,and definitely the least attractive iPhone to date.
That makes absolutely no sense. You're clearly not even aware of the form, feel, or overall shape of the 5c, let alone the brilliant manufacturing process.
There is nothing unattractive about it at all....Except maybe the color choices if that matters to you.
A single piece of molded, rounded _anything_ is better than a flat aluminum back, squared off to a stainless steel band, with chamfered edges.
The iPhone 5/5s is the worst iPhone design Apple has ever deployed. I've owned all of them. The 4/4S was pretty close to ridiculous with a similar design and glass back....but at least it not have the chamfered edge which is microns thick with raw unfinished metal beneath.
