Freezing leftover rice from take out Chinese is a great way to get a head start on homemade fried rice. The key with homemade fried rice is to start with COLD rice, grains separated.. by the way, frozen rice defrosts quickly.
Also, you can re-steam leftover rice with a little water and covered for a quick side dish for picky eaters (my son will not eat potatoes, but loves rice).
