I just sent out my iPad 4 for repair of the glass. My in patience led me to purchase the air. I came upon an unused open box for 489.00 so playing around with the air didn't really notice that much of a difference and I do really like the solid feel of the iPad 4 so I was going to return the air and just keep the 4.....that is until I streamed video via airplay. No stuttering no hiccups smooth nonstop playing unlike with the 4. I am a cord cutter so this is important to me. Now I have to decide what route to take for selling the 4
