I tested the H1 when it was first presented. It didn't impress me, really. A bit too heavy for a 6x4,5 camera, and much too expensive. I also used it for a seminar I gave with a digi back (Hass. was a sponsor, the camera was hardwired and a guy from the company manipulated the software, so the images showed directly on a screen)...
Anyway, with that kind of money, I could buy a Rollei 6008 with 6x6 ability AND a 6x4,5 revolving, reducing back THAT CAN DO LANDSCAPE AND PORTRAIT shots WITHOUT HAVING TO HOLD THE CAMERA ON ITS SIDE !!!!!!!!! And great Scneider and Zeiss lenses, too...
Holding the camera in the "wrong way" is very annoying in middle format, since the cameras are bulky and heavy. So, a 6x4,5 camera has to have a revolving back in order to gain my sympathy... Of course the Rollei is heavy and bulky too, but if you don't have to hold it in an awkyard position, then it handles just fine....
On the other hand, if I wanted a 6x4,5 simple camera I would opt for the Pentax or the Contax (then in production). Nowadays someone can go for the Mamiya. Much, much cheaper stuff.
I don't see what the H2 has to offer to me more that the H1 had (after a quick visit to the website)...
