Like many people on here, I'm looking to buy one of the new rMBPs and reading all the various reports and weighing up the options. I've just been watching the following video and at 14:15 he talks about getting static electric shocks and sparks coming from the HDMI port when using the short power cable. https://www.youtube.com/watch?v=pzBqnzDKnVM I found this quite amazing and wondered if this was a common problem and if so, why anyone would use the short power cable if it caused these problems. He also states that he was completely unable to install Windows, which I will need for other aspecs of my work. I'd be interested in other people's comments.
