What was once envisioned as a simple calculator watch has drastically changed into a modern day computer. A company called Eurotech thinks everyone will have a wrist-worn PC (WWPC) as the eventual PDA replacement, designed for the use of on call jobs where you need to communicate or find out information fast, such as healthcare and emergency rescue. A more durable model could probably be used by police and military personal. 

The 7 ounce wrist PC can hold up to 1GB of any supporting cards fitting into a SD-card slot. The WWPC comes with 64MB of SDRAM and 32MB of embedded flash. It has 2 cell Li-polymer rechargeable batteries that are built into the adjustable and flexible wrist straps which have a battery life of up to six hours in "fully operational" mode, and eight hours in normal circumstances. WiFi, Bluetooth, and infrared networking are included along with USB host and device ports, built-in speakers, and a headphone jack. A very dashing 2.8 x 2.2 inch daylight-readable LCD touchscreen and a direct-access keypad with covers the top of the wrist.

Another neat feature of the WWPC is that is has a patented orientation sensor that can detect if the users arm drops it will await in stand by mode conserving more power. That is not the only sensor that is embedded in this device, but when a user becomes motionless built-in GPS receiver which will act as transmitting beacon.
