Its Vista 64 bit or osx leopard on a MacBook Pro. Its a built in bluetooth adapter.

So i'm quite flexible with operating systems.

The reason why i want to PAN with my Laptop is because it has a stronger WiFi antenna than the N810, and its standing on a good reception spot.

With a PAN i could take my N810 to bed (i know this sounds wrong) and surf the web from a practically 0% WiFi spot.

So this could come in really handy!
