During Apple’s October 20th Back to the Mac event, Apple announced the latest MacBook Air models.

The updated MacBook Air comes with either an 11.6” or 13.3” high-resolution display, and a 1.4GHz or 1.86GHz Intel Core 2 Due processor (expectedly). They are substantially thinner and lighter than previous models, support up to 30 days of battery standby time, and range in base price from $999 – $1599.

The biggest technology change with these new MacBook Air models is they don’t include a physical hard drive.  Apple has instead opted to install flash memory directly to the motherboard for storage, just like the iPhone/iPad.  This flash storage is available in 64GB, 128GB, and 256GB configurations, and presumably can’t be upgraded easily after purchase.

This flash storage is separate from memory, and all base MacBook Air models ship with 2GB memory, upgradable to 4GB.
