This is very preliminary but let`s go with it.
Here`s what we`re looking at regarding the new Macbook Air:
Ram will start off at 4GB and move up to 8GB on the high end, so lets look at the 11" first:
Base Model: MD223LL/A - MBA 11.6/1.7/4GB/64FLASH-USA
Better: MD224LL/A - MBA 11.6/1.7/4GB/128FLASH-USA
High End: MD845LL/A – MBA 11.6/2.0/8GB/256FLASH-USA
Now moving on to the 13" model:
MD231LL/A – MBAIR 13.3/1.8/4GB/128FLASH-USA
MD232LL/A – MBAIR 13.3/1.8/4/GB256FLASH-USA
MD846LL/A – MBAIR 13.3/2.0/8GB/512FLASH-USA
Looks like some models will be getting 256 and 512GB SSD. Allegedly these will be Samsung 830 series drives which are pretty damned fast.
Stay tuned for more updates.
