Hey Hey Hey, I have D9, but I don’t get any chicks so far… LOL~~~
The most convenient thing of D9 is its size. You can wear it like a watch during the dive trip. I don’t see any divers who were wearing the big SP wrist computer out of water.
It has three gas switch function, but you cannot get three transmitters. Ouch, I realized it after buying D9. In addition, this function is for the deco diving, but in reality I am wondering how many tech divers are actually using this watch and function except the gauge mode and bottom timer. I also haven’t use this gas switch function during the deco diving.
The digital compass is a gimmick if you are doing a lot of navigation. It will gives an instant direction, but not for the navigation. Don’t get me wrong. The navigation and search and recovery are the major part of my diving type, scientific diving.
I don’t have any bug or error on the computer. Only thing I am sick and tired of is the Suunto DM SW. It has an endless bug and fix.
I don’t think it is worth for $1500, but you can get it lower than that. If I do it again, I would buy other tech oriented computer for me. But, if I can afford to do it again, I will buy it for my GF who is a rec diver.
In addition, my GF is much better than any chicks out there…. 
Just my 2 psi.
