Why use lightmapping with I have the Unlit shader?

So I happened to be playing around with the shaders for one of my textures and noticed one called unlit. I toggled it and removed all the lights from my scene. All the game objects and textures were visible without a light.

Is it ok to use unlit shaders if I’m not concerned about baking shadows etc.??? … is the unlit shader a performance hit on mobile?

The unlit shader is there for when you don’t want dynamic lighting or shadows.

It is perfect for use on mobile games.

The unlit shader it´s the best for perfomance on mobile platform. And it´s compatible with lightmap. You can view the result selecting Edit → Graphics Emulation → (GLES 1 or GLES 2) if you are in iOS platform.

Thanks so much!!!
