Technology evolves at a frightening pace. So much so that before new technology comes out on the market, even newer technology has outdated it.
There are some interesting things coming up in 2009. Just some examples:
Premium Notebooks, Wii MotionPlus, Windows 7, $99 Blu-Ray Player, new Apple iPhone, 4G Networks, 32-inch OLED TV, Wireless HDMI, USB 3.0 Devices, and better Android phones.

The light sabre in film gives me unreal impression. According to my idea, a light sabre cannot be parried by another sabre.

It also seems to cauterize wounds when it slices off body parts.
