We've been developing on Seam for 3-4 months now. Initially, we used client-side state since server-side was definitely broken (by whom, I don't know, but it was broken!). We developed a ton of functionality and client-side state was working great for us but we knew we'd have to switch to server side at some point. About a month ago, we upgraded Seam (it was Beta 2 at the time) and switched to facelets 1.1.11. We tried out server-side state. Everything was still working just fine. Other than web.xml STATE_SAVING_METHOD, we did not have to change anything! I think you'll find similar answers from other users. As far as I'm concerned, server-side state works just fine!
