So, it's been a good couple days since people started complaining about the battery life on the 2.6Ghz 15 inch MBP and I'm wondering, how are your results? Did it get better? Worse? Stayed the same? I'm on the fence and I'm wondering if the 2.6Ghz is worth the price and if the battery life is impacted compared to the 2.3Ghz. Also, how's the heat on the machine?
