I am using my laptop more and more on the road and with that, I am starting to use more things that are attached to the unit. The one thing I've consistantly used is the first generation Delorme Earthmate GPS unit. It attached to the laptop via a serial connector. While it was always a reliable performer, Delorme came out with a new unit that ran by either a USB connection or with a self-powered Bluetooth adapter. (Since that time, they've come out with 2 new models; one is USB only and the other is a Bluetooth unit.) When I got my new unit, I was given a bluetooth adapter for it from my boss who tried to use it on his motorcycle with a Palm Tungsten. Unfortunately for him, the Palm screen could not be seen in bright daylight.
So in order to use it, I had to get a bluetooth adapter for the trusty 'ol laptop. Most of the add-on Bluetooth adapters connect via a USB port. Since I was going to use this in a car, I was most concerned about the laptop being moved around and either snapping the adapter off or even breaking it.
This Belkin adapter connects via the standard PC-Slots that are on almost all laptops. Because of that, the bulk of the adapter is inside the laptop. Only a small tab sticks out of the machine and in my opinion would be far lass prone to damage or disruption. The actual card is an elongated Compact Flash card and it comes with a Compact Flash to PC-Slot adapter. For me, this was an added benefit because my Canon EOS professional Digital Camera uses Compact Flash memory cards, so it can serve double duty for transferring my photos to the laptop and then running the Bluetooth adapter. Since most laptops have two PC-Slots, this adapter is very thin, so it could be left in the laptop while a second card (like a wireless card, USB2/Firewire adapter, etc.) occupies the other slot.
Intallation was very easy and straightforward. Once the device was installed and operating, it was very easy to connect my GPS unit to the laptop. This is one of those devices that does its things transparantly in the background and they either work or give you all sorts of fits. This devices does its job effortlessly and is almost invisible.
I found it to be a great device I'd reccomend and it was offered at a great price that made it even more a sensational value to me. I would highly reccomend this to anyone that needs to add Bluetooth to their Windows-only Laptop.
