Hello to everyone. I am a new kid on the block here who will be requesting assistance. I have the desktop, laptop, and smart phone so I thought I would complete the collection with a tablet, which I have no knowledge. To start I am looking at a Samsung Galaxy Tab E 7" 8GB. Most likely I will use it for browsing an twitter, facebook, etc. I notice that some tabs are just wifi others with a line connection. This is my first question, which way is best??????
