I'm very tempted to buy a 770 but I have some questions about power consumption. 1. Can you throttle the CPU on the 770, manually or automatically? 2. What kind of battery life do you get during various tasks (movie watching, surfing etc.) 3. Has the upgrade to OS 2006 impacted the battery life? 4. OT: How are the screen in sunlight?
