I was thinking about how the Lumia 1020 specifically targeted photographers and the 1520 targeted people who want a bigger phone. Idk about other carriers but Att only has one rugged waterproof smartphone which is the samsung galaxy rugby pro. There is also the galaxy s4 active but it isn't as rugged and reviews complained that waterproof didn't work. The rugby runs android 4.0 and my friends was super slow and laggy. Nokia should build a rugged waterproof windows phone and release it on all 4 major carriers. That way people who need a good rugged phone will have one. Considering nokia does a great job already building top notch long lasting phones; who want's to see a rugged waterproof Lumia? (If you have any other suggestions about niche phones please post in this thread. I think nokia can get marketshare by targeting niche markets until wp gets better (8.1 looks promising) and and gets more apps.)
