Here's a quick look at the freebies built into the 3DS.

Will be pubbing a much more detailed look at these features later in the day, but an important thing we discovered is that a lot of these built in apps can run in the background.

For instance you can be playing Zelda Ocarina of Time in 3D, suspend the game and start taking notes, then jump straight back into the game.

Very useful idea.

Stay tuned to Kotaku's 3DS page for a day full of updates, interviews and videos.
