i read the 11.6 inch Macbook Air rumor when i was in the airport carrying my 15 inch laptop...i really hope this is true and if there's any time they should release this then it's NOW!
Why not an optional black and white e-paper screen for the Air, for those who need legibility first? The demographics of ageing eyes in the U.S.: The fastest growing age segment is - those over 100 y/o. The 2nd fastest growing age segment is those between 90-100. The 3rd fastest growing segment is those 80-90. The 4th fastest growing age segment is those from 70-80 years old. 5th: 60-70. So, the screen-making industry would do well to wake up and smell the demographic coffee. Time for some innovative R&D to push screen readibility "to the next level".
They're never going to make an e-paper only model of any Apple device. I would bet real money that the next iPad will have an e-paper mode that will switch the screen to high contrast black & white for reading ebooks. I'm skeptical they would ever build that feature into a notebook, but I do see the wisdom of it.
Apple offers a hi-res screen option that, what?, 95% of its customers don't buy. I would never buy it. I would never buy the matte option either, as for legibility, it goes too far. But it's no skin off my nose that they offer those options. Similarly, if they offered a screen option on one notebook like e-paper, to help the large fraction of the population with imperfect eyesight, it wouldn't be any skin off the noses of the 95% not choosing it.
The current MBA keyboard is ~10.5" wide, by ~4" high. The 13.3" screen is something like 11"x7". A 11.6" screen is about 9.7"x6.2".. so you could have a full size keyboard if you've got a large bezel, and NO real border around the keyboard. A 10" screen would be more like 8.5"x5.3"... needing almost a full inch around the screen to be wide enough to cover the keyboard, even with the keys going to the very edges.
That's just a matter of size, not productivity. Full-size keyboard is why I paid so much for an MBA, instead of getting a netbook. I've tried to type on a netbook... and it's seriously cramped. I'm a software developer by trade and hobby, I have relatively large hands, and I also touch-type. I don't think a cramped physical keyboard would really be any better than a cramped capacitive virtual keyboard on the screen. Can't really touch-type in either case. Given the kind of window explosion that occurs in most IDEs, I have a hard enough time with the MBA screen making things fit; a lower resolution would be BAD. A same resolution, smaller screen would quickly become eyestrain inducing, though the crazy brightness of Apple screens helps there.
