Apple's Retina Displays are drop-dead gorgeous. But be careful what you wish for.
Like many, I got the third-generation iPad because of the 2,048-by-1,536-pixel-density Retina Display. And, like many, I didn't see a huge difference at first.
That was then. Now it's painful to pick up my Dell laptop with its 1,366x768-pixel 13.3-inch display and Windows 7 fonts (note: font-smoothing utilities go just so far).
