They're great little game birds. Like with most fowl, I'm sure there's been different experiences among us. One chicken egg is pretty much the equivalent of five or six quail eggs. So, I think Digger is right, that you'll need quite a few of them if you're planning to have those eggs for your breakfast. You can breed them and sell them as game. Of course, you can also use them as meat and keep them for their eggs. They require more space than you might think and they don't usually pair well with pheasants and other fowl which tend to pick the quail off one by one. You might need to get a permit to raise them since they're wild birds.
