in order to turn off the programs, you just have to press the button that lets you switch programs (by default it's the far right button on the bottom row of buttons) and then when it pops up the list of programs running, just press and hold the stylus on a program name (like when you do the copy/paste thing for text). it will pop up a list of commands, such as close program, close background programs (will close all programs that do not have focus), close all programs, etc. the only program you can't close is the today screen, if I remember correctly.
