I'll say that after using the DHO800 for a couple of months now, a few hours a day, I've long forgotten about the things I thought would annoy me. The vertical screen thing is an absolute non-issue. The only thing I still want to change is to remove the little icons on the vertical 'measurements' window on the right of the screen so that I can see 8 or 9 items at once instead of 5. Not that it's that much of a deal to scroll it up and down with your finger, but I'll get around to moding it one day. Other than that, I'm a happy camper.
