Both iPads have only small amounts of available RAM (256Mb and 512Mb) and thus does not really allow Multi-Tasking

It just freezes the Apps in the background; only the iPod Music Player and a few 3rd Party Music Apps are allowed run in the background

Because of Memory leaks, it's best to Reboot the iPad at least once per week to avoid problems with multiple frozen apps in the background; you do this by:

a) Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.

b) Press and hold the Sleep/Wake button until the Apple logo appears.
