I did but that's just speculation so i was wondering what the price were on release of DS :)

Notice I said software likely contributed. But the games themselves did not sell the hardware. The hardware sold itself with the help of some software. As you yourself pointed out the DS lacked any real good software at launch. You couldn't prove that software sold the DS anymore then I can prove that hardware alone sold it. But I can prove that hardware was a deciding factor and definatly contributed a ton to the DS's sales.

I for example bought the DS based on hardware alone. I did buy Mario64:DS soon after purchasing the DS and played it but it was the dual touch screens that had me. Infact PictoChat was a huge deciding factor for me. I didn't even buy a game launch day I just played around with the touch screen and the dual screens had me day one.
