I really didn't think I'd use it much at all, but I have yet to spend the money to invest in a portable Bluetooth device.
I love the Trusted Bluetooth on my home and work computers then in my car, but my phone will only automatically connect to the car so I would have to manually connect the phone to the computer for it to work.
I have a couple of NFC tags set up to connect my phone to my computers though so that is painless. I've found the Skip to be great use for unlocking my phone to actually use these NFC tags.
The Skip is also great use when I have to use my phone for single tasks when I'm out and about so away from my lock free zones.
Once I got these systems setup I changed my phones lock from an easy pattern/pin to a strong password so I'm much more comfortable with my phones security.
That said, I don't know if I would buy the Skip. I'm having trouble figuring how to secure it to my person, because the fabric of my pants makes it fall off fairly easily despite the magnets whenever it's bumped. The Skip dropped three times since yesterday morning, including once while getting out of my car this morning. I wouldn't want to spend $20 on something I'dlikelylose. I'll see if my phone will recognize one of the dots if I put it in my wallet.
