-location of game slot {bottom left}
-C-stick in upper left portion of the inside bottom section
-2 new shoulder buttons: ZL & ZR
-the Home button is now just the house symbol
-Start and Select appear below the X, Y... buttons instead of besides the Home button
--To add, all 3 Home/Start/Select buttons are now much smaller
-stylus is on the bottom right section, instead of on the righthand side
--the stylus itself is different enough that a normal XL stylus does not fit into the N3DS stylus slot
-power button is now on the bottom right section, instead of on the inside bottom section
-volume slider is connected to the top screen, on the opposite side of the 3D slider {i.e., volume is on the left side; 3D is on the right side}
-Volume slider clicks when you turn it all the way down -- like how the 3D slider does in the XL {and the N3DS}
-no WiFi switch that I can see
--also, 3 of the indicator lights {power, charging, and WiFi} are on the bottom
-the device, I think, is slightly shinier than a normal XL
--fingerprints show up close but not from a short distance
