Intel's Architecture Group VP Rani Borkar is making some bold claims about the upcoming Haswell chipset: that it will allow laptops to deliver 50% more power out of existing batteries. 50% more runtime is an incredible claim and if true, may single-handedly drive increased laptop sales as customers jump to upgrade.
He attributes the miserly battery usage to lower power requirements and better power management. I have to test a Haswell device before I can believe such a grandiose claim but it is music to my ears.
In other words, wait a couple of weeks before you buy that new laptop.
