AFAIK Blu Ray hardware doesn't affect battery life at all. Don't know why it would. Actually playing back a Blu Ray disc probably sucks battery power just because it has to hit the CPU and/or GPU so hard,
You hit the nail on the head there.
but it's still longer than 30 minutes! And even if it was 30 minutes, not everyone uses their laptop unplugged exclusively.
Defying the point of a laptop.
So? You don't need 1920x1080 or higher for Blu Ray to be useful. I don't even want that resolution in a tiny laptop screen.
Maybe not, but thats all its available on. Again you hit the nail on the head. Why would anyone want that level of quality on a small ass screen with crappy sound? When they could buy a bargain bin laptop, and a 42" Full HD and blu ray player for the same price.
Maybe not much...yet, but they've been slow every single time there's a new optical technology. They sort of ignored DVD, CD-RW, DVD-RW, etc. Always late to the party, and it has always cost them sales in the past.
Again if it starts hacking at sales, they'll introduce it, it isn't so they wont yet.
Also all kinds of people watch movies on their laptop. Probably MOST people watch movies on their laptops at least sometimes.
Yes, DVD's or downloaded content.
People who watch movies and TV are not a niche market. Granted Blu Ray is just a sliver so far, but it's adoption has apparently been even faster than DVD, which was faster than VHS, etc.
Yes its a big adoption because Sony shove it down your throat when you buy their console. No one could care less about computers though. Apple's main customers are those who are technically challenged, they have a HD TV and Blu Ray player, they don't want to watch movies, let alone blu ray on their small computer or laptop screen.
How so? Presumably the point of watching something on a laptop is that you want to watch something and don't have your TV and full sized player available.
Again, they wouldn't care about Blu Ray.
