Graphics = 5 stars (when playing a decent game) the graphics are good, but this depends greatky on which game you play. Best graphics are currently on splinter cell, street fighter is in the middle and ghost recon is shockingly bad.
Sound = 4 stars - it does have good quality sound and is not as tinny as its predecessors but it is very quiet.
Inbuilt software = 4 stars - the software that is on the 3ds is good. there is a camera that takes 3d pictures, a mini game using the camera creates 3d games from placing a card in front of the camera, and a game that captures peoples faces and puts them onto the enemies of in the game.
Upside - sturdy little machine, you can feel the quality it no longer feels as if its going to snap (like the ds lite) big screen, inner and outer cameras. 3d mode is very good for a handheld. the new charging system is a lot better where you have a power tray and just put the ds on it and lift it of when charged no more playing about with cables as you can give it a permanant place.
Downside - The 3ds is only half up and running currently, there are software glitches and it does freeze. The 3d camera can be quite difficult to set up as it needs natural light and a clear view of somewhere that is 20 metres away, so it can be a challenge. The 3d mode while good seems to wash out the colours and the brightness of the screen - so yes it is 3d but the colour intensity drops hugely. I have found that when playing the mini games moving the ds around can be difficult also as the screen is heavier and they still have not sorted out the hinge! when you move the ds around or put it down with a tad too much vigour the screen bends at this awkward angle and you can hear the plastic squeek so do take care. Finally the stylus has been moved and is now in the most awkward place possible (at the rear towards the left under the screen when the ds is open).
Lastly - I do love the 3ds but at present it is not complete! the nintendo store is not up and running so you cannot access that or see any games, demos etc so that is a minus.
The internet browser does not work either, it makes this big hooha about setting up the wifi when you first turn it on for it to say that it will not work without an update (which is not out until late may / early june).
ps if you wait it will probs be cheaper by then and also all the software will available! tbh i do feel a bit conned by this and wish that i had waited
