Ok, so this tool has become a critical piece of my overall productivity arsenal. The product is billed as MiFi, and is actually a portable, wireless access point which can be used individually or shared with up to five total devices. The unit, which measures 3.5″ x 2.3″ x 0.35″, is extremely compact and weighs just about 2 ounces. From a spec perspective, it can be used continously on battery up to 4 hours by one device and has a wireless range of up to 30 feet. This means, that if your PC is using the device for internet access, you can be up to 30 feet away and still have a connection. A 4 hour capacity implies a great deal of mobile freedom, since the device also functions while being charged. In a pinch, you can carry the device in a jacket or shirt pocket, power it up when needed and access the internet using a PC with wireless capability, an Ipod Touch or any other wirelessly enabled device. In actual use, the startup is almost instantaneous and connectivity from a PC perspective is equally fast. With this unit, you really no longer need to buy individual cards for each device, this device can be shared. For me, a good analogy is how I use my Garmin GPS. Since it is a portable unit, it is independent of the car I drive – when I need its capabilities, I bring it along, unlike a GPS which is built into my car, which can only be used in that car. With one device, I have one service plan, one monthly bill and when any support or maintenance is needed, I only need to do it once.
