Ole Begemann on the design of his 6 plus:

The way the display glass curves around the sides is stunning and feels great in the hand. There is almost no discernible seam between glass and aluminum. It must have taken Apple’s industrial design team tons of work to arrive at this level of workmanship. The curves also make the built-in swipe gestures feel a lot more natural.

I am in 100% agreement here, and in fact his entire ‘design’ segment of his first impressions are spot on.
