Sebastiaan de With of Cocoia has posted another of his UI roundups, this time focusing on Apple's evolution of the iPhone interface in the form of the brand new iPad.

He notes the expanded icon size of 72x72, and as-yet-unused 64 and 320 versions, along with more "earthy" metaphors, and since he designed the one for Classics, weighs in on the very similar looking iBooks.

Conversely, he's not a fan of the new "popover" UI element, calling it kludgy. And feels the repugnant, inconsistent look of the iPad iTunes application takes no advantage of innovations from either the iPhone or Mac, and is a visual punch-in-the-face. He's also worried that the lack of encouragement for resolution-independance in iPhone app development (though TiPb's heard Apple does indeed stress that) will make the iPad's 2x mode a blurry mess.

For our part, TiPb's wondering how much of these UI changes, good, bad, and ugly will hit the iPhone with either iPhone 3.2, or iPhone 4.0?

What do you think Apple should move over to the iPhone, and what do you hope they keep far, far away?
