From our initial tests it has been a God-send!!! It beats what we have been tied to for years ... Crystal Reports! It was a pretty straight forward setup as long as all of the needed requirements were met. It has been up, running and stable for us for over 9 months now.
We have developed many reports for in-house and client-side projects. Works really well with SQL Server.
As for AS, we plan on our first implementation in a few months. We would try to move sooner but other projects have our attention right now.
Thanks
