If you like to paint with multiple brushes, you can hold these in your fingers together with the palette. This means they're immediately available to use, without bending or stretching to reach them. It also solves the problem of where to put a brush with paint on it without marking a surface.
You can hold one or two brushes, or a whole bunch together with a cloth for wiping a brush. Your dexterity is the limit. You'll find that with practice you stop consciously "holding" the palette and it'll just rest in your hand.
