If you find having to lug around a laptop a hassle and tablets insufficient for your needs, then maybe you can consider the Eurotech Zypad WL1500 as a viable alternative. It's a fully-functional computer that you can wear on your wrist so you can do whatever it is you need to do without having to start up any other devices.

The Zypad WL1500 is cloud-enabled and sports a 3.5-inch TGT touchscreen with a QVGA display.

The backlight is controlled by an ambient light sensor that automatically adjusts the screen's brightness depending on the amount of light available in your current surroundings.

One major concern would obviously have to be the battery life. No one wants to get stuck with a device that has a battery that gets used up way too fast because then that would defeat the purpose and overall appeal of a wearable computer. However, the Zypad WL1500 can run for up to 8 hours, which I think is good enough, considering that my laptop can only run for a maximum of 4 hours on its battery. Users can also hot swap the battery without the fear of losing any data and charge up the device via USB when needed.

The Eurotech Zypad WL1500 was designed to give users functionality and access to information without having to sacrifice mobility. As such, it is equipped with topnotch wireless capabilities as well as built-in GPS tracking.

As for the keyboard, the Zypad WL1500 only comes with one that has 12 keys so I don't think it would be practical to use when you have to type a particularly long document. As Eurotech recommends, this would definitely be useful for people in the logistics business who need to be constantly updated on what's happening with their shipments. It would also quite useful for people who are in the medical field, as well as those in the security and transportation sector, or for everyone who would need immediate access to information on the go, for that matter. For these purposes, Eurotech can easily integrate a 1D/2D bar-code reader directly onto the device.
