well I am coming up to 20 years in Basel and I have no intention of leaving Basel. A lot of jobs have, sadly moved to Zurich, which means I might at sometime have to commute regularly to Zurich. I would certainly never consider living there....I think the Basel attitude to Zurich has worn off on me.
Have fun, Basel is a great place....big enough for lots to be going on but small enough for you to be able to go out and meet people you know whilst in town.
