Yes I have now got mine also ... there is often a lot of critical comments regarding Hasselblad on the forums and i can only guess these folks don't use/own one.
You are wrong
Many of them work with , or have or had one...
As to the H5D improvements, small changes from the H4D but when you use one for work not play they make your life easier and that means you can concentrate more on the shot and less on the camera.
I am very happy
If it is true...
From what you write, they were able to fix all the errors. Perfectly !!
Congratulations. I wish that the equipment has been used by you for years.
