I have the GPS, but not the IPAQ (yet), and it's a shame that there is no port for Psion/EPOC (that's what I currently use my GPS with), cos that's the only PDA I have right now. I'd love to sort out some kit, but I'm not sure I should just yet.

If I did, it would probably be an IPAQ 3760/3650 with a single PC Card sleeve, an Orinoco Silver card (where did you get yours, btw - I read that you need an old firmware to be able to use promiscuous mode), and a Compaq RS-232 serial cable to hook up to the 9 pin cable that goes to my eTrex.

I'm really curious to see what you were getting when you were near the places you mentioned. I guess if you strapped all the necessary gear to the handlebars of a bike and rode around, you could collect quite a lot of APs! I guess your tour just took you down Damrak and into Kalverstraat - I wonder what else is out there?
