I think the 13 M2 MBA is 1199. So 1399 for the 15 M2 MBA?
Imore is right, it is unlikely the 13 and 15 will be different in general specs. But the specs are great as is for Air:
Super slim high quality design
1080p web cam
Excellent speakers especially for a thin laptop
20 hour battery (crushes competition)
No fans, no moving parts.
Very good display (though 60hz)
Industry best CPU and GPU Performance for a thin bezel
