I've been blow away with it, it's Delphi brought from the dead :)
It has been a real pleasure to use and I've come to appreciate the productivity that it brings, as this open source IDE is on par with what I remembered from early Delphi versions and, amazingly, I feel this is the cleanest way to target mac and linux GUI apps today (YMMV).
It's a shame that there is no support on SWIG for freepascal but it will get there eventually.
So, kudos to the freepascal and lazarus teams and thank you very, very much!
