I still use a fair amount of the novelties weekly if not daily a couple of years after they've been introduced. For example the fireman's poles are actually a great way of moving around. There's some nice outdoor spaces at the office too (including a rooftop terrace), they're just not shown on those pictures.
Does anyone work there just for the interior design? Of course not. But I don't see how they'd be annoying, and will take the Zurich offices over a beige cubicle farm any day.
