Too little, too late. Free Wifi was interesting a decade ago. Nowadays in most countries 3G is so cheap that nobody bothers trying to find an open access point. I currently pay 4 Euros per Gigabyte per month (or optionally 9 Euros for 9 Gigabytes) - that's all, no other monthly fees, no minimum charges, can be (optionally) combined with a voice plan. And in addition most newer laptops provide (optional) builtin 3G modems, so you don't even need a USB modem to use your 3G connection.
