Yes, I was just going by the specs issued by Sony and the one review that briefly mentioned the 3N's flash.  I wish there was some way to to compare them in the store.

And yes, I was debating built-in vs. removable.  I didn't realize that Sony sold another flash for the NEX.

If you plan to frequently use flash indoors as you mention, I would definitely choose an external flashgun...greater power, easier to fit diffusers,  ability to "bounce" flash off walls or ceilings to achieve less harsh lighting and so on.

Also, a built in flash is quite close to the lens and is apt to cause "red eye" effects.
