power consumption
“The 3G chipsets that are available tosemiconductors work reasonably wellexcept for power. They are real powerhogs - So as you know, the handsetbattery life used to be 5-6 hours for GSM,but when we got to 3G they got cut in half.but when we got to 3G they got cut in half.Most 3G phones have battery lives of 2-3hours.”
Steve Jobs is the co-founder, Chairman and CEO of Apple Inc,
“Longer battery times allow the customerto download and enjoy more itunes ($$$)and I do not care if you wait some secondsmore to download them!”

Stand-alone: Cheetah• Optimized on speed only
– It is the fastest of all land animals and can reach speeds of 120km/h.
• Evolutionary Trap
Cooperation: Hyena• Optimized to work together
– Hyenas live in very large clans between 10 and 100 members for cooperative hunting
cooperation in nature
– While resting the cheetah risks a 50% chance of losing its catch to other predators, such as the lion, the leopard, the spotted hyena and baboons.
