To allow Apple again, to sell us the new THINNEST, LIGHTEST notebook (with a smaller battery).
Don't sell your 2012 just yet.
My worry as well. Don't leave the battery the same and get 10 hours, make it smaller and get the 6 hours. I don't need it thinner, I do want ipad length battery on a MacBook Air.
EXACTLY! There's no "thinnovation" in running out of battery when on the road. And it's not like anything out of Apple in the last 3 years was considered "thick" so most users would appreciate better battery life over thin bragging rights.
That said, I dont think theyll change the air design yet so this may be good news for 2013 models.
I guess I'll be the rebel in this thread and say that I actually look forward to seeing a thinner and lighter Macbook Air, even if it does mean compromises in battery. Of course, as long as it equals the same battery life as the current generation MBA, then it will be seamless for customers, as have all Apple products have been that that have gone through thinning over the years.
