A. To me, that point is at 1" thick and under 5lbs.
Cool

. For me, its less. Currently at 2.4 pounds, could go lighter.
B. I'm not going to be all that envious of people with a .3" improvement in laptop size when it cannot match what my laptop can do.
Its slightly more individual then that. For me, my laptop is used purely for work- wireless internet (email, looking up information), SSH to other machines, telnet into routers etc etc. I can't think of any "features" I want it to have that would increase its size. The extra size would be for features I don't want or use.
Battery life, durability, features, HD capacity, Graphics capability, processing capability, increases in every other capacity that may have otherwise been spent in making the machine smaller.
1) Batterylife is a big, huge key. But 14 hours sounds pretty good to me. Anything over 5-6 hours is fine by me.
2) Durability also very important, but THIS IS NOT RELEVANT. We KNOW they can make it durable at this size, yet you keep bring it up like it would have to be weak or fragile. It wouldn't not have to be, because other machines of the same weight class are not.
3) What features? Can you be more specific?
4) HDD Capacity. Don't care

anything over ~20GB is fine, because its a work machine and I don't work with sound or video.
5) Graphics? Likewise, don't care. It needs to be able to connect to a projector, so it needs VGA out & sVideo/Composite might be nice. Thats it,
6) Don't need much CPU grunt- the most basic dual core chip would be nice, because multitasking is nicer with two cores but 1.5 vs 2.3ghz? Don't care.
7) What other capacity?
You're still not realising that the biggest problem with this machine is that you don't suit it. That's fine... theirs lots of other models for you! Super thin, super light is a DIFFERENT product category & the people interested in it have different priorities- and this laptop looks damn awesome for that. Light, thin, lots of batterylife. Sounds perfect.
