Moto Maker is an awesome website that will let you totally personalize a Moto X. You want a red and blue smartphone with yellow accents? Hell yes you can have a red and blue smartphone with yellow accents. And now you can get it for $100.
You could already get a $100 Moto X on Amazon, but not a customized one. Of course you have to sign a new two-year contract, but that's pretty much expected, and you're saving $100 off the original $200 price tag. A half price phone with all the colors and memory and personal touches you'd like? Yes, please. [Thanks, Basil!]
