I own an Apple Macbook and have been very happy with it. Recently, I upgraded my nearly four year old machine by doubling the memory and adding a bigger and faster hard drive to it. But, as this article shows, that may not be possible for some Apple computers in the future....

I hope that is not true.
The new machine design is designed around a different set of trade offs than older machines.
For example, in machines from roughly 2008 and earlier, the rechargeable batteries are good for around 500 full charge/ discharge cycles, or about 2 years of very heavy use, or 4-5 years of typical home use.. The newer lithium polymer cells are good for around 1500 charge/discharge cycles, and should be good for 5 years of very heavy use, or a decade of home use. (after the rated number of cycles, the battery has 80% of the capacity it had when new.). If the battery doesn't need to be replaced as often, or even at all over a typical machines useable life, then it could be practical to eliminate the space needed to build a user accessible battery compartment, connectors, and a removable battery container meeting puncture and heat resistance requirements. This stuff represents about 30% of the volume of a typical battery subsystem in a laptop computer. If it can be eliminated, and the battery molded to use the space saved (along with any other free space) then the time the laptop can run between charges can be made considerably longer.
Similarly, there is no reason that a FLASH memory storage device needs to have the same size and form factor as a hard disk drive, or use relatively bulky SATA signal and power connectors. Building the drive on a dense compact board tied into the system using low profile edge connectors can cut the volume needed by 2/3rds.
The MacBook Air and Pro models both make these trade offs.
Battery replacements are done by swapping out a portion of the case that has all the high wear components attached (battery, trackpad, keyboard). The old assembly can be recycled or remanufactured as appropriate.
Folks seem to like the smaller, lighter machines, and these are the engineering trade offs needed to build such devices. It's quite possible to design machines where lots of parts are individually user accessible and swappable, with a different set of trade offs, such as thicker cases and reduced battery life in exchange for the space to hold bulkier modular components.
Most end users don't touch the inside of their machines after purchase. Not laptops, or desktop all in one boxes, or traditional towers. Rather than design for the small percentage of users that do open the box, Apple has chosen to leverage the behavior of the vast majority of their users, maximizing usability and minimizing weight and thickness of the laptop.
It's all just design trade offs. Oh, and past history shows that there will be third party battery and FLASH storage replacements for these machines.
Disclaimer: We have three laptops, from 2002, 2004, and 2006. I keep these running through the usual methods, although they aren't used much any more. Two have relatively new batteries, and one has had the disk drive replaced. I don't have any plans to buy more, as I find the iPads, combined with a desktop server system, to cover all our current needs.
