With the retina display, does a UIView with a frame of 100/100 points actually have a bitmap of 200/200 pixels?

+1  A: 

Yes. Memory-wise it's x 4.

So when I say I want a font with 20 px height, I actually get one with 40 height?

@openfrog - You don't specify fonts in terms of pixels, but points. On old iPhones 1 point = 1 pixel, but on the Retina display 1 point = 2 pixels. For future displays, this scaling may change to something else.

I strongly suggest you read the part of the iOS App Programming Guide dealing with resolution independence.
