Why does Apple use multiple PNGs (that aren't even crushed) instead of a single compressed SVG? The hardware is certainly powerful enough on OS X, and probably the iPhone/iPad...

Apple uses transparent file system compression (since Mac OS X 10.6.x+, the kernel decompresses the compressed data). The file system compressor uses the deflate algorithm (zlib), like PNG. Vector-based images are not always possible.

That's cool about the FS compression, but I still don't get why they can't use vector. :/

I guarentee a lot of the images are vector in their original format so they can make them as big as they want, but as said above, I would rather have like 100MB extra used then processing vector graphics. It's not like 100MB ever made a difference for me.
