It is new technology. When it is mass produced, the costs will be lower per GB than today's fastest SSDs. It is great information, but it's not yet relevant for us. In 2012, we will all be talking about an MBA with 256 GB SSD in low-end and 512 GB SSD in high-end model.
Same thing with OLED displays. Sure they're expensive without mass production, but I believe the MBA could get one with its next form factor revision. When mass produced, they will not cost much more than a standard LED/LCD.
I cannot wait for these technologies to catch up with us...
