(Can't edit the post above) But, of course, Skype issues aren't because of their UI nativeness. Their UI layer is... well, tolerable. Heck, I'd be happy if all I'd have to complain about Skype would be a crappy UI.

But I don't think UI implementation has to do anything about why we love it so much. I mean, missing calls and messages every other week, random desync between clients and all the usual rituals that every other group call starts from (you can hear them accompanied with chants "can everyone hear me?", "$name are you here?", "tell me if you see my screen" and "let me drop the call and restart").

i think i was still overreacting to prove a point. everything you're saying is right.

my point is, even if i concede native is "better" or whatever, the difference should be negligible for most apps for all users (let alone "most" users).
