Hi Travis

I found this D-link Wifi on sale for $29 a few months ago just check the usual suspects for sales like Staples, Office Dep, Buy.com, Tigerdirect etc. I saw one internet cafe in Italy that offered an ethernet port, NONE In Germany because the cafes want to run their metering/monitoring software and control what you do with a "locked down" PC.

Also you can Not assume they are running XP SP2 NOR plan on using "built in " drivers that may or may not be avaialable.

I will also try the http://maemo.org/maemowiki/USBnetworkingWinXP
USB cable approach but I think it is more problamatic on the n800 side.
This approach tricks XP into thinking the N800 is an ethernet device.

I like the Dongle USB Wifi approach because it is the easiest & fastest
approachto setup and remember at some internet cafes you can pay 2-3 euros ($4) per hour so you want to get on the net grab & send you data and get off. You can easliy recoup the cost of the Wifi dongle by saving time not doing HOTMAIL or equivalent at Net cafes.
