The new Nokia Lumia 820 looks nice, but if the resolution is 480×800 or RAM is 512MB on the production model. So far, I like the 820 render better. 4.5″ is too big for me, and 4.3″ is on the high end but doable.
Looks like 820 has a bigger sensor than Lumia 920. Could it be like 820 is a full PureView with WP8 and 920 is only half-baked PureView Lumia. Wondering such a small sensor on back of 920.
