PlayStation 3's initial production cost is estimated by iSuppli to have been US$805.85 for the 20 GB model and US$840.35 for the 60 GB model. However, they were priced at US$499 and US$599 respectively, meaning that units may have been sold at an estimated loss of $306 or $241 depending on model, if the cost estimates were correct, and thus may have contributed to Sony's games division posting an operating loss of 232.3 billion (US$1.97 billion) in the fiscal year ending March 2007. In April 2007, soon after these results were published, Ken Kutaragi, President of Sony Computer Entertainment, announced plans to retire. Various news agencies, including The Times and The Wall Street Journal reported that this was due to poor sales, while SCEI maintains that Kutaragi had been planning his retirement for six months prior to the announcement.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Assuming iSuppli got the numbers right, how much of a loss did Sony take for every 20 GB PS3 sold in the U.K.?
Ah, so.. unanswerable

All of the highways into Wenchuan, and others throughout the province, were damaged, resulting in delayed arrival of the rescue troops. In Beichuan County, 80% of the buildings collapsed according to Xinhua News. In the city of Shifang, the collapse of two chemical plants led to leakage of some 80 tons of liquid ammonia, with hundreds of people reported buried. In the city of Dujiangyan, south-east of the epicenter, a whole school collapsed with 900 students buried and fewer than 60 survived. The Juyuan Middle School, where many teenagers were buried, was excavated by civilians and cranes. Dujiangyan is home of the Dujiangyan Irrigation System, an ancient water diversion project which is still in use and is a UNESCO World Heritage Site. The project's famous Fish Mouth was cracked but not severely damaged otherwise.

Ah, so.. fewer than 60

Dumbwaiters are small freight elevators that are intended to carry food, books or other small freight loads rather than passengers. They often connect kitchens to rooms on other floors. they usually do not have the same safety features found in passenger elevators, like various ropes for redundancy. they have a lower capacity, and they can be up to 1 meter (3 ft.) tall. there's a control panel at every stop, that mimics the ones found in passenger elevators, like calling, door control, floor selection.
