@Siberien. It's a financial angle from my CIO. If we have say 1,000 web views, and 1 is on that rare device plus they may not be buying the cost of getting the web page to view spot on isn't worth it.
Another view is if you got it to work on iOS, Android, Windows and Apple's Safari then it's going to look OK on that last rare thing or at lease better than run of the mill sites.
My buddy thinks that web developers can often OCD about this. But at some point you need to get to the next thing.
