I know, I know...another bitmap...blah. Never claimed to be a professional anything, but you should get the idea.
The LCD is on a pivoting hinge so it can be "closed" for clamshell like protection. When closed there's a smaller status screen that tells you whether there's an incoming "Wii Mail", you're charging (and how full the battery is), playing audio media or if you're in standby/pause/sleep durring games. When you open the screen you can access the large battery if need be.
When you flip the LCD for playback the system can be held vertically or horrizontally. Due to the well placed D-PAD you have access to it in either variation with your left thumb. There is also a vertical & horizontal L Button, also for easy access. The right hand is for using the stylus (in either vertical or horizontal form) or for the traditional face buttons in vertical form. Vertical form may look to be cramped or top-heavy, but the unit's heavier components (swivel hinge, battery & rumble) are located in your hand(s) and there's more of an ergonomic bulge towards the bottom for easier gripping.
To answer those who want analog control and/or traditional control (for playing VC downloads) in the wider horizontal mode, there is a Wii EXP port on the bottom of the unit to plug the Nunchuck, Classic controller or even other Wii peripherals!
There are also a variety of other features such as:
-16x9 multi-point touch widescreen LCD
-Wii performance on the small screen
-Wii user interface & menu system
-1GB of internal flash storage
-SD Card slot & media playback features
-rumble feedback & tilt control
-Virtual GameBoy (not only have access to VC & WiiWare titles, but now an array of portable classics will be available to download)
-plus, minus & home buttons just like the Wii (allows you to quickly reach the main menu, adjust volume, rumble, lighting, holding & other settings)
-built-in Nintendo playing card reader...no extra peripherals needed to enjoy your favorite card-based (DBZ, PokeMon, Yu-Gi-Oh, etc.) games
-camera for communication, multimedia recording & motion tracking gameplay
