Mossberg is just repeating Apple's hype that the new MBA is somehow inspired by the iPad. There is no fundamental difference between this new MBA and the original one that predated the iPad.
This is significant because it proves that Apple creates hype. A lot of their marketing is hyperbole.
Significant differences between the new Air and old:
- significant;y smaller
- significantly better battery life
- significantly faster (especially if you were using the HDD version, and also because of the GPU)
- significantly cheaper
- significantly more USB ports
- significantly longer "sleep" time (sound like its actually like a fast hibernate)
- significantly more RAM
