I've pre-ordered the lumia 820 but until today I haven't gotten a reply from carphonewarehouse. This has made me considered cancelling my order and looking at other options. Among the windows phone 8 devices, the only other phone i'm considering is the samsung ativ S.

The lumia is priced at 380 pounds compared to the ativ S speculated 440 pounds.

My question is, with the much better screen resolution + size, battery life, internal storage, lighter weight, thinner body and flash-support, should I choose the ativ S over the Lumia 820 and pay 60 quid more?
