I didn't vote for any of them, since the current MBA is a great, if not downright amazing machine but with second rate sales and second rate interest from the public. They don't always have the MBA out on the sales floor at the Apple store, and the other other item that is not on the floor all the time is the 30" inch display/monitor.
What would make the MBA achieve 1st string starter status with Apple would be a lower price. The PC netbooks, and many people's abilities to put OS X on it, has greatly diminished the lust many once had for the MBA.
Also, for some but not me, the iPad has come in as small, light, good screen, and fitting some people's mobile computing needs and taking the MBA off their wish list.
EDIT: I voted for support for 4 gigs of RAM. I was unaware that the MBA didn't have that. 4 gigs is what makes some games and the Adobe suite work very well. Sometimes if one is multi-tasking too much with big apps, 2 gigs of RAM can slow everything down. The Macs I have used with 4 gigs of RAM seem to handle everything I have seen thrown at them.
Of course, I am no fast as the speed of light gamer, who always needs the bleeding edge graphics card and the highest amount of RAM possible, but the MBA is not trying to compete as a gaming machine against an overpriced top of the line Alien laptop ($5,044.00 for mid-level, SSD, Alien without any warranty over the included one year). A real gamer would at least want a top of the line extra monitor/display at home thus adding to the cost which then makes one want to only play games and do nothing else. Add two monitors for peripheral vision and some speakers with a real bass response, then the internet price is over $10,000 dollars.
If MBA could get 4 gigs of RAM, then it could be a combination professional laptop that can run both OS X and Microsoft Windows, be ready as a graphic design machine, and pretty decent gaming machine for a better price than anything the PC side has. I currently like the $1799 SSD MBA and that fits my needs.
And for the extreme gamer who likes to slam Apple, they can always call my friend/old boss who caters to rich kids, and adults who have not grown up, and hook up a ten foot screen to their laptop or desktop to make their computer game seem like a giant video arcade came with an insane Bose and JBL surround sound. Starting price, about $30K. But if you want to invite 20 of your best friends to come and watch a movie at your house instead of hitting the local movie theater, then it becomes a cool option. I have to admit playing pacman on a screen taller than me is almost spiritual.
