Really? I'm forced to use an S3 as a work phone, and it sucks. The pentile display bites (I read all my books on it, so this really matters to me), and the stock ROM was very unstable. I'd much rather have a Lumia 1520 or HTC One Max.
im forced to use iphone 5 for work and it completely sucks.
screen too small, have to login whenever i want to do anything.
ive had htc, samsung s2, s3, s4, samsung note2, note 3, android, apple, and the best OS by far is windows. nokia with windows lasts 3-5 days without a charge, smooth, fast, slick- some large screen HD models out there..but the apps selection isnt great. not a biggie though since it has everything i need.
its a shame MS missed the boat on it. im an open soure fan, so admitting that windows OS was the best, took me some time. have gone back to iOS and Android several times- but keep coming back to Windows OS.
its definitely the most polished and fluent OS- and the nokia phones are the best value for money, and dont need extensive hardware for a great OS experience. The bottom of the line Nokia with windows outperforms any android/apple midrange offering.
