I see a lot of people complaining about how much battery life would suffer if Macs had Blu-ray drives. How often would you watch a 2 hour movie on battery power? Where are you at for that long without access to AC? Camping in the woods?OK, I jest, but come on. Doing anything CPU or GPU intensive is going to drain the battery quickly. I see lots of people playing video games at my uni. They are almost always plugged in at the time. And the price of Blu-ray drives? Who cares if they are expensive? There are obviously plenty of people willing to pay for them. Let them have a BTO option.
It's not just the GPU and CPU, it's the optical drive that is a huge drain on the battery. Any relatively forward thinking person would have ripped video to the HDD so they don't have to run an optical drive or cart around a bunch of discs.
But that still hasn't addressed the physics involved. I suppose if Apple can buy the patents to TARDIS they could even get a PS3 into a 1" notebook for under $500.
