Yes, my laptop weighs about 12 pounds, but cmon, what is 12 pounds? If 12 pounds is alot of weight for you. Time to get the gym and loose that 300 lbs of body fatI'll take my 18 inch screen and hardware performance over underpowered tablet Laptop.
I have joked about this, when did five pounds become heavy? My 17.3" laptop is in the five to six pound range I believe and it feels light. I would have no issue carrying it around. I understand though who do want light small devices.
Fullsize laptops are not really THAT heavy.
But hey its all about what you need? With the rMBP I think its insane to kill the ODD, and ethernet for 3/16th of an inch.
Thin is good and all, however not at the cost of usability for such a minor difference.
Ok, gotcha.
Better streaming is already here. You can get 4K streams off of YouTube that blow BD away. It's not mainstream - still a few years away from that - but it's coming, and it will get here far faster than the 10 to 20 years it'll take the optical side of the business to agree on a new standard.
Another factor that comes into play is how important is it to any given person, some are fine with HD cable and own nothing, some are still fine with SD and a CRT because it is just not that important. I like owning content yet there may be a time when that is just not that important, and if netflix etc.. stopped showing said show? Oh well? That could be the answer many would say.
Hard to say how quickly higher quality mainstream media will get here, not sure if people will be ready for another upgrade any time soon, another new format, player, television? And if people can hardly see the difference they may not even care.
