I don't have an 'internet plan' - well, technically I do, you can't choose whether you want to have just voice, or just messages, or just data or just... on any service in my country - you get the whole deal right from the start (you pay some miserable sum to have 3G enabled, tho, but that's like $1.5/mo). But the data is extremely costy as there is no 'unlimited data' package - with prices such as $1+/MB you'd hardly be doing any surfing if you appreciate your wallet. At most I connect to 2G/3G data just for the IMs and if I need to check some page urgently.

However, there is a fair share of open WiFi networks throughout my city, especially since the largest ISP gave their dumb users open WiFi routers so you can hitchhike at almost any place on the city I actually don't miss having unlimited data that much - when I'm on the move I'm driving so I can't really use it (apart from listening some internet radio, which I don't listen to anyways), and when I'm stationary chances are that I can hitchhike on some WiFi, so not having a real/usable data plan doesn't hinder the device and does not affect the experience that much. After all, I'm writing this post on my N900
