The most obvious thing about Dell's ignorance-promoting product page for the XPS13 (the differences are only defined in marketspeak) is that there is still no SSD available:

However, I'll keep the low-end version in mind the next time I'm shopping for "America's Best Protection." Oh wait, they all come with that. Hrm.
Are they really hoping to get a piece of the Macbook Air pie with this?
