My team (aestasit.com) has also been using Asana for the last 3 months and, overall, we are satisfied. I'm not going to summarize the good and bad aspects because the previous comment does it egregiously. Asana is fast and it feels like a native application on both my Mac and Win box. The feature I miss more is the possibility to assign tasks to multiple team members. I'd also love to see a native iOS application. Asana team recently released a mobile-compatible version of the site that works great but I'd still prefer a native app. I have also tried out Trello but it has a "toysh" feeling to it and Asana just has more features.
