SlipperyBrick: This is an interesting combination of peripherals if nothing else. A company called Navilock out of Germany who specializes in GPS products has produced a Bluetooth enabled mouse that also acts as a GPS receiver. This is convenient in that if you are looking for a powerful GPS antenna and you are going to be using a mouse anyway, you can now just get them both in one device adding less clutter to your workspace.The BT-451 mouse from Navilock connects to your PC, laptop or other device that supports Bluetooth wirelessly for both the mousing and the GPS. The company boasts that the powerful antenna under your hand will perform better with getting indoor signals than most GPS receivers, and obviously performs well outdoors, too.
The BT-451 is currently available at stores in Europe for about €79.
