John - Thank you - it's enlightening to see that both you and MtnMan actually liked the ghosting in the last shot ! I'll have to see what it looks like without for a comparison.
Harriet - thanks ! Yes I also liked the library - I thought the exhibition piece itself was very cool, more like an art exhibit than something from the future. DPHDR - I do like the hand alignment option (you can let it auto-align if you prefer) and usually use it. Other than that I found the interface cleaner than Photomatix and I also like the tools which seem more intuitive for me personally. As you say though it's good there are choices out there so we can each have something that suits our own style.
MtnMan - Thank you for your comments ! I'm glad you liked them and thanks for telling me which ones you liked and - just as importantly - which one you didn't !
