A lot of little things, mostly. Yes, there are temples and villages to raid, which are an easy way to quickly get some food and maybe even armor and a diamond or two if you're lucky, but it's still a head start on finding that desirable building spot, taming pets (which should be much easier now that wolves don't despawn), finding other generated structures with treasure in them, etc.

Me, I'm hunting for an ice biome right away. Gonna need a lot of ice, and a lot of space for my plans.
