I can understand - that is the only real grumbling i've heard is the cost. However you have to bear in mind that you're buying a computer not just an advanced depth timer.

There is a market out there for a cheap freedive only style computer that has a number of alarms but no computer or logging functionality.

Time will tell about the D4 but I suspect that it will sell well due to it's combined scuba/free functionality and good looks.
