It is an improvement in terms of specs.
I would like to see these things implemented next time before i would buy one.
I would ideally like to see it lose a bit more weight i also think that Apple should probably do away with the MBA to allow for this.
Also i would like to see dual graphics to allow for max battery using both the intel chip and dedicated graphics.
I am unsure about the battery life it seems to have taken a little bit of a hit.

Also i would like Apple to add in at least an express card so that you can use mobile broadband if you want. The usb dongles just look plain ugly. I would love it if Apple added in WWAN and i do think that is the way to go but i cannot see that happening.
Maybe they should have just sold this as a pro to allow for the things like an express card slot.
The screen is a bit to glossy for me but i guess i could live with that.
This notebook is close to being what i wanted and Apple is going in the right direction.
