I want to buy a tablet that will let me connect to a projector to show powerpoint files and also use an android app to allow my android phone to work as a remote control. Does this count as multitasking? Listening to music (mp3) while surfing the web - is this multitasking? I have read the android 4 allows for "better" multitasking. What counts as multitasking? Will Android 2.x or 3.x do the things I have just mentioned?
