Here's the thing. You bought when you bought. At the time you rationalized the cost and it was "OK". Don't blame Moto for your timing. If we all waited for 3 months after a phone launched we'd all get a lower cost.
And look Apple is the KING of gouging people (IF they refunded your 100 which I doubt) they would make up any concessions in initial price by charging you out the @$$ for accessories that are proprietorial plugs and what not.
You have what is in my opinion the best phone available. Love it and move on.
Or do what I did call your carrier and raise heck about everything else and get some credits.
