After writing an SD card image, is the remaining space usable?

Forgive me if this is basic, because I'm used to writing CD images, I'm not sure how this works. The Raspbian image is about 440MB (zipped at least). If I write the image onto a 16GB card, will all the remaining space on the card be usable for data?

Running 1080p video from within XOrg smoothly

The 1080p examples that work outside of X.Org run very smoothly on my Pi, but within X.Org they don't run very smoothly at all at the moment. Given that X.Org is currently not GPU-accelerated, this is understandable - but with the hardware…
