Yes the Motorola G is now live for purchase on Amazon UK, for a very reasonable £159.99 - we don't have a clear picture of the config just yet but to say it will be high spec would be a bit far fetched.
Motorola will unveil the device but we suspect there will be no SD Card slot, and stock Android Kit Kat will be pre-loaded. It does sport custom colour backs though, and a quad core CPU, until tomorrow we can only assume the S4 chip set will be included.
If youre feeling brave, then pre-order today :) Amazon UK Moto G listing.
