I guess we shouldn´t compare £ to € prices... then we would have to compare wages and tax in UK and Germany... and so on.
As a matter of fact Google is selling the Nexus 5 (32GB) version in Germany for 399€ and the Moto G (16GB) is sold for 199€. Therefore I would recommend to set the price for the Moto X (16GB) somewhere inbetween. (Maybe around 299€)
I don´t see an
advantage for the Moto X over the Nexus 5 and we all know other Flagship phones are knocking on the door.
I guess the Moto G will sell very good in Germany - it´s been highly recommended by local tech bloggers. However the Moto X (without the stylish Moto Maker feature) won´t live up to the praise - too little to late. And don´t forget the German Angst
(Always listening device... No Sir!).
