Russian Billionaire (I hate him already) Roman Abramovich recently took delivery of his $2 Billion yacht (the worlds biggest and most expensive yacht) which is a gadget nerds paradise. Some of the details… two helipads, two swimming pools, dance floor, 6 foot wide home theater screens in all 24 guest rooms, retractable roof, mini submarine, etc…
One of my favorite features is a anti-paparazzi device that scans for camera sensors… when it finds one it blasts it with laser light making the photos not come out. Genius.
