If you didn’t know this yet: vienna is one of the coolest places to geek at. Nice town, cheap rents, cool people, free universities, art, recreation. And, most important: free wifi nearly everywhere.
Try it out in vienna: open your mobile computer and in 50% of all times, some nice person will have intentionally have left you an open wifi access point. Yes, these people believe that the world is a nice place and that you can surely use their wifi to read mail and google something up. There is free wifi in most of the cafés I frequent and there are enough public places like www.muqa.at with free wifi.
All this geek-friendlyness of vienna has led to many people using plazes there to check where they are and where wifi is. Vienna is on place four in an in-official statistics with having the most online plazes. Vienna is on a head-to-head race for place four with New York, perfect. San Francisco is second, first is Berlin.
