Hello
I agree with Travis, Net cafe PCs are too dangers for using financial websites
and its also important to beable to download/upload content onto the N800.

I also investigated a 3rd method of net connection via the N800 USB cable
http://maemo.org/maemowiki/USBnetworkingWinXP
but this required hacking on both PC & N800. This would certainly be cheaper because you do not have to buy anything else.

Also remember which ever method you use it must NOT require a reboot of the
NET Cafes PC . I found in Germany, not only would the Cafe manager be very annoyed if you tried to reboot, but many cafes wipe your PC Hard drive after each session and copied a fresh Win XP OS onto the PC.

Using the D-Link Wifi USB , I did NOT follow the instructions to install with their setup program first. I plugged in the USB adapter and then "fed" it the drivers. It recognized the
DLINK and put a Networking Application in the Tray at the bottom right of the screen, without a reboot.

So it is important to do a "dry run" at home with your adapter at home to simulate the "XP Cafe environment "before going out on the road. If you buy a USB Wifi adapter locally from Circuit City, Staples etc, if it does not work the way you need it too, you can always take it back.

Best of luck and let us know what method works for you WIFI, Bluetooth,or USB cable and WHY.

thanks
