Just received my PN51E7000. I was surprised that the Amazon shipping through CEVA also included "white glove" setup. The driver brought the unit into the house, removed it from the box, attached it to the stand, and powered it up to verify operation. He offered to remove the box and packaging, but I wanted to keep it just in case I need to return. This service was included in the free shipping.
As for the TV itself - the picture is stunning, but I'll have to play with it for a few days.
Note that it does NOT have a VGA port for connecting a computer - only HDMI. On the plus side, it does have one HDMI port that support audio return channel (ARC) to send sound from the TV apps (e.g. Pandora) back to the A/V receiver without using the digital audio output. Also, Samsung doesn't seem to have an Amazon app for streaming video.
Four stars for now, but I may upgrade to five after I've had more time to judge the picture quality.
