We didn't order far enough in advance. Ours are not arriving til the 9th & 10th. Apparently, if you order a 4G one it arrives a day later than the Wi-Fi only one.
I am greatly looking forward to getting mine as is my wife. The big downside is that mine is coming on a Friday when I work til 10PM so I won't even get to play with it till Saturday cause I will have to install my backup on it Friday night.
