I want to purchase an Android based Tablet, but I am not realy familiar with the Android OS itself (although I am computer savy). Does the Android OS have PC based software to manage, sync, backup the device? My son has an Android based Motorolla phone and it did NOT come with any software, but maybe newer versions do. I have not been able to find any information on this. Also, are there any strong feelings about whether it is better to get the Samsung 10.1, or the Motorolla Xoom or an Asus tablet? One of my priorities in a tablet has to be the ability to store PDF files on the device itself and read them. It has to be fairly easy to manage the PDF file storage, to add new files and delete unwanted files.
Any help would be...helpful.
