Well, I really appreciate Nokia's work, both in software and hardware. It's obviously the best pack in terms of software in any mobile platform.
However, when I switched to WP a month ago, I decided to go with Samsung (Ativ S), for a few reasons:
? Screen size. I had a Nexus 4, so I thought that slightly smaller devices would be a downgrade. Apart the 930, the Lumias are between 4 and 4.5 inches (the 1320 and the 1520 are too big for me).
? Technical assistance. Nokia, in Brazil, is very limited, since it only counts with two places in my state. Bad things happen, so better be safe than sorry, and I heard not so good things about these assistances.
? Removable battery and SD support. Some Lumias have, others don't; add this to the screen factor and that's a deal breaker for me.
The 930 would be my choice after all, even violating some of my requisites. But, hey, in Brazil it will cost my kidneys and my lungs, considering I don't have the money to pay for one. And I'm very satisfied with my Ativ, both in HW and SW, since my biggest interest is Windows Phone itself.
