What's the point of USB ports? What would you really use them for? Transferring any content from your camera can be done with the $29 camera kit. Syncing any media can be done with the included USB cable via your Mac or PC. All your other data can be stored in the cloud.
I ordered the Wifi only version. I might not always have access to the Cloud. I keep files on a USB drive that I was hoping I could just "grab and go" and not have to worring about having to sync before leaving. But whatever.
