Oh ok, but good to know :) I always wanted to visit the baltic countries once, and I usually travel around with public transport, so I'd have to consider that when planning I guess.

Well, public transit between major cities and in/out of country is OK. Online timetables are reliable enough, you can get tickets online etc.. No live GPS tracking though :) But tourist attractions in smaller towns or, worst of all, in between them is kinda.. tricky. One of the reasons why hitch hiking is not dead.
