Never having owned a smartphone or tablet before, I figured it would take a little time to figure things out; and it has.

I got my 7.2 this past tues.  Once I figured out that I needed a file manager app (which I got for free at the google store) downloading music and video from my computer to my nexus was a piece of cake. 

To connect my computer to my nexus I used the charging cord I got with the unit and it seems to transfer video at the same quality I see on my computer.  For music, once my computer and nexus were hooked up, I went to 'my computer' and located the nexus and clicked it.  And then it was as simple as drag and drop. Done

For my DVD's I downloaded Handbrake and transferred them to my computer in mp4 format.  And then proceeded to do the same thing I did for my music transfers.  I watched parts of the videos on my nexus to check for quality and they came out great.

I don't know what reason I need to get a $20-30 micro usb as the one that came with the unit seems to work fine. Am I missing something here?

I'm new to the world of nexus or any tablet. I should have a nexus 2nd generation in my hand 7/30 via best buy and UPS. I currently have a mobile family plan with Verizon, and I am considering upgrading to a Samsung S4--my first smart phone.  I've read that I can use a S4 as a hotspot to connect my nexus to the internet.  I'm interested if anyone here has experience with this, and what their experience was.  Thanks for any help.
