(1) Is it really a problem that apps can't be pixel perfect on the 6+? How unsharp are we talking about? Are there workarounds such as device detection and an additional set of image assets?

(2) Will Apple aim to re-enable pixel-perfection in next year's iPhone release? Was this just a stopgap measure due to yield challenges inherent to display manufacturing?

1- We'll have to see a device to know for sure, but I expect his will not be a problem at all. For my apps, I'm going to do nothing, but make sure we support the additional point dimensions.

2- I think this is doubtful. The first time I saw a WWDC presentation about Resolution Independant graphics was in 2003 (maybe 2002.) Apple's been preparing for this time for a over a decade. The iPhone just was a bit too skeumorphic in its early versions resulting in a focus on raster assets rather than vector.

Either we're all going the Paintcode way (authors of this post) or Apple is going to have to start taking CSS or SVG or some vector format for its assets.

I think this is more likely than tying displays to a rigid multiple of the original iPhone screen size.

(1) The iPhone 6+ has 421 dots per inch, which is in the lower ballpark of printing resolutions where you don't have pixel perfection either. It's not going to be a problem.

My Nexus 5 (4.95", 1080p, 445 ppi) does the same, and to me it looks fine.
