Don't you want Turkey in EU :-) ?
Well, I am of two minds about it. Eastern Europe has just joined the EU and needs to reap the benefits of their economical and political efforts before we "spring" another country on them.
Given its economy and population, Turkey will change the EU economical scene almost overnight, and I'm worried about the newest members discovering that they just lost their fiscal and cost-of-life advantages after just a few years.
