No, I generally share DWW's aversion to polyester in tailored clothes.
But there important exceptions imo: hot, humid weather or other harsh conditions, like year-round bicycle commutes or so-called adventure travel. And then I only like blends, not full on polyester. Although, Uniqlo has some golf pants that felt pretty wool-like... Their low rise prevented me from trying them on though.
I should also mention that Old Navy (of the Gap) currently is selling 51 linen/49 polyester t-shirts. So far, I like the fabric.
