p.s. I assume I was a bit wrong in definitions (read that article 3 months ago). Not thousand times better battery life, but still allows for the same battery life within way less form-factor + extremely fast charging.

The article says,

The energy density is slightly lower, but the power density is 2,000 times greater.

The article author has never taken an elementary physics class and doesn't understand the difference between net energy and power. Energy density is the amount of energy, represented in Joules, that can be stored. This is akin to the battery life of your device. Power isn't measured in density, but for the sake of argument let's ignore that. Power is the measurement of the rate at which energy can be released from the power source, measured in Watts. So, what does that mean? These batteries are essentially awesome capacitors, improving on their ordinary cousin's lackluster energy capacity. Read on.

The end result is that these porous electrodes have a massive surface area, allowing for more chemical reactions to take place in a given space, ultimately providing a massive boost to discharge speed (power output) and charging.

Which makes sense. Lithium is the element responsible for actually storing energy - energy density. The article made it clear that the electrodes have just been made porous, thereby increasing their surface area and allowing them to increase charge and discharge rates. Which brings me back to my original point, that energy density cannot be altered but the rate at which batteries may be recharged will be improved drastically.

I realize I was a little snappy last night (my Galaxy Nexus's Android 4.3 update broke root, and I got pissed) but my argument remains sound. It's not your fault that this article led you astray - the author clearly has no basic understanding of electricity, and instead expounded and speculated on a subject that he was not well versed on.

It'd be an inch thick, too. Samsung's 1TB SSDs are in a 2.5" enclosure, which is almost thicker than the entire MacBook Pro. The limits of NAND density have been reached, so you're not packing more storage into the same amount of space. I think 768GB is as good as you're getting.

In actual fact, most of that 2.5" enclosure is empty. Samsung use just 8 NAND packages to reach that 1TB size.

Crucial also offer a 1TB class SSD and they use 16 NAND packages to get there. The current Crucial/Micron NAND packages do look a bit smaller than the ones from Samsung.

But Micron are moving to 16nm MLC NAND:

We have a little way to go before we reach the limits of NAND density. I'm not saying the technology is limitless, but I give it a year, perhaps late 2014 and we will see a 2TB 2.5 inch SSD and a small 1TB SSD for either the rMBP or other pci-e SSD in the NGFF / M.2 format.
 
Why does your dream macbook have a generation old Nvidia GPU? , if you're dreaming, add a 765M or something.

You're right - NAND isn't completely saturated yet. But the limits are real enough (and close enough) that alternatives such as FeRAM, PMC, and mRAM are being investigated.
