Since December 2012 I was using my Nokia Lumia 920, which in my opition the best Windows Phone at this time. Last Friday I had the chance to pick up my Nokia Lumia 925 in one of the Swiss stores.
I really loved the Lumia 920 and Nokia did fix the parts which needed some improvements. The Lumia 925 is much lighter and thinner than the 920 and the new design together with the AMOLED display are really welcome. of course if you are already using a Lumia 920 it’s maybe not a really big difference but form some the Lumia 925 fixes some issues with the weight.
In my opinion this is the best Windows Phone you can buy at this time.
