OK ... four years for DAZ Studio's development so far.  It probably took the same four years for Poser to reach Poser 2 or 3. How much "name recognition" did Poser have BEFORE Poser 4 was released ?  And how much of that name recognition was due to the fact that it was pretty much the ONLY program of its kind for a long time coming?  That's why DAZ Studio (and now other similar posing software like Quidam) are compared to Poser ... Poser was the first.

So you're not comparing apples to apples.
