I think adder has summed things up nicely.
Just to add though that in case you do get the NEX, it doesn't come with a telezoom lens like the 50-200mm lenses.
If you get the Sony double kit - 18-55mm + 55-200mm lenses then you can get a Minolta 50mm f1.7 easily in the used market.
Sony also has a 18-250mm lens which is optically as good as the Nikon/Canon equivalents but does not focus as fast as the Nikon/Canon 18-200mm lenses.
