Android may very well be a good OS, but nothing about it screams must have.
Samsung reels people in with hardware specs alone then they throw countless features at you that do nothing but drain your battery faster (airview, etc.).
I carry a Note 3 as well as my 1020 and always use my 1020 as my primary phone. The real estate of the Note is excellent, but I only have it for the S-pen and some apps that either run poorly on Windows Phone or are not there at all.
I love the 41 MP camera on the 1020 and see Samsung's "camera phones" as a camera with phone functionality rather than the opposite. Sure, it looks like a phone, but only to put it in a niche market.
I will stick with my 1020 as my phone with an incredible camera and carry my Note for my paltry Android needs.
