Hi Just a couple of quick things really as i'm new to Android. Firstly when i connect my tab to pc via usb does the tablet need to be turned off or can i have the tablet turned on throughout and also use the tablet whilst they are connected? Secondly, I want to transfer some books from pc to tab via usb connection and i'm curious as to what the process is, As i have multiple e-reading apps, As well as the app that came installed on the tab, Will the books be transferred to each app? Or will i be asked at some stage where i want the books to be sent? Thank you for any help.
