I love Europe, but for being so developed, it's amazing how many places there people still think smoking is 'cool,' and 'a symbol of freedom.'
I do like Vienna, but I think I'd choose Hamburg if I had to choose a city in the German-speaking world. Or Berlin - only slightly less cosmopolitan, but the tech start-up scene is kind of happening, and the cost of living is cheaper.
That said, Vienna struck me as a very nice city - very livable for its size, although the climate leaves a lot to be desired.
It's probably something I'll never understand, since (to me) it is an obviously bad idea to inhale the carcinogenic burnt residue of some paper and leaves which has well-known, major long-term health impacts as well as compelling you to continue doing so, and to pay for the privilege (not to mention the damage done to others, and the smell all through ones clothes, etc.). Eurgh, the big cigarette companies (and their ad agencies/publicity departments) are some of the scum of the Earth.
