Extending the Surface Pro battery life

With all the naysayers dissing the Surface Pro's battery life, has all of that influenced your thoughts on getting it after all? Do you guys think it's possible to tweak the surface pro to have just as long battery life as that of the Surface RT? because I think it is. I'm not sure about the capacity of Surface Pro's battery capacity compared to those of ultrabooks at the same price-point.. but I'm assuming that not all hope of getting the Surface Pro through an entire day's of usage is lost. To those geeks out there who love the tinkering their devices... do you see this happening in the coming weeks?
