theres no MBA air with an HD and if i'm not mistaken they all have 4GB of RAM as standard now+Trying to understand pricing here. On the 15" MBA...
- Replacing the HD with an SSD add $500.
- Adding 4GB of memory adds $100
But the rMBA is only $400 more than than the legacy MBA, meaning upgrading the screen to retina costs -$200.
