Howdy all, Sorry if this post is in the wrong section (I'm new to the forums). I recently bought myself a new Samsung Galaxy Note 10.1 Tablet for Xmas and am loving it so far. This is my very 1st tablet, but i have always owned Samsung products from T.V, Fridge, Cell Phone, Camera ect....Love Samsung. I have been exploring all the features of my new tablet and am slowly picking up on stuff, but there are a few things i read about on the forums here which got me to thinking (forgive my noobness on some of these questions). 1) What exactly is/does Dual Mode Wifi mean & why is it an important feature? 2) What is "Wacom Digitizer layer" mean/do? 3) I have seen some talk about "BT 4" What exactly is that? 4) My tablet is Wifi only - Will i get the new Jeely Bean update coming out or do i have to download it from the internet or take it to Best Buy for them to install it???? Any tips and/or tricks you can inform me about are very welcomed!!! Thanks for taken the time to read this post, and again sorry about the noob questions!
