Why Did Samsung Use Super TFT Instead of Super AMOLED for Its Galaxy Tab?

Even though the TFT screen was mentioned the first time we heard (however unofficial) of the presence of a Samsung tablet, it was still disappointing to see there wasn't actually a Super AMOLED in the final product. But why not?

As a Samsung exec told of in a Q&A session at IFA, they chose Super TFT over Super AMOLED (pictured) because "the TFT is a little more optimized than Super AMOLED in terms of power consumption," also listing price as being a contributing factor too. [OLED-Display]
