The rates are the same for GPRS and 3G networks. Officially Wind has no 3G roaming agreements, but in reality it has. I can tell for sure that I could use 3G in both Germany and Austria, while if I'm not wrong AndreA used it in Switzerland and Belgium recently. I think also in the UK Wind has 3G agreements, surely with Three, but also with other operators. I think that all 2G agreements should include 3G as well in the nearby future.

Wi-fi data cards are a good choice, and I think wi-fi is the best deal in many hotels, airports and public places. Here in Italy we still have very little access points in cities, but abroad it's much different, and not hard to find some free public access.
