Tried to put too much in it. Be something for everyone. Basically too heavy, too many bits and pieces and bloated.
There's a difference between listening and a world wide suggestion box. Or don't you think so? Apple have been accused for a long time of not listening. They have also been lauded for giving people want they didn't know they wanted. And succeeded time and again. Example: iPhone. We knew we wanted a smartphone, but they didn't go and ask everyone how to do it. They did it themselves and look what we have now, from iOS to Droid to Windows etc (and all of the phablets, tablets and bad experience hybrids).

Your opinion. Hundreds of millions disagree
