The nio Bluetooth device makes sure you don't leave home without it.
"It" can be whatever device you have chosen to pair with the nio using its security software with a device via Bluetooth.
Consider the nio your device's burglar alarm. Once connected, the devices are secured as a pair, even if not in close proximity. An alarm on both devices sounds once they are separated past an acceptable distance.
Users have to do a simple software install from the nio download site and then pair the devices. All this takes just a few minutes.
When setting it up, the most important choice you will make is how far you want to allow the devices to be separated before the alarm sounds.
It's about the size of a flash drive and is powered with a built-in battery recharge via USB. A reset button is the only control on the device.

With all the apps available for the iPhone to use while in a car, the NewerTech Window Mount for the iPhone 3G and 3GS can be a handy accessory.
The best feature is that while driving you will be in a hands free mode when using mobile apps or phone calls.
For installation, simply mount the media player to any window, which gives you full view of the screen. It also gives access to the touch screen, but of course users would never use this while driving.
It's made with a vibration resistant, flexible arm to adjust for most any view and NewerTech suggests it can be used just about anywhere in addition to autos. For example as I write this, the super vacuum adhesion suction cup is holding my iPod touch on an airplane tray table.
It's suggested to use it with the Apple iPhone 3G and 3GS models only but obviously my touch is having no problem coming to a rest in the handy accessory.
