Always been a supporter of 1x. I have a fight about it with my girlfriend at least once a week. Damn she almost left me once because she couldn’t stand looking at my pixelated designs. :D
All jokes aside there is only one issue with 1x that we cant get around and that’s working with invision sync.
Although I do hope I’m just being ignorant and someone will politely explain how to make 1x designs export at 2x (or whatever) when syncing source files with invision.
If not, that’s a huge deal breaker for us, since invision sync saves us tremendous amount of time… and no client wants to look at blurry prototype on their beautiful iPhone. :D
