Or maybe just maybe there are people who don't specifically need many of the things you described and like the specific things the MBA does bring to the table? Or does it make you feel better to broadly label every single person who might be interested in this as a.... well, you know how you put it?
No discreet graphics? You won't find those on ANY 3 pound under 1" thick laptop. The X61 has GMAX3100 graphics; hell, the Sony TZ still is stuck with Intel GMA950 graphics.
No DVD burner? Won't find that on the Lenovo X61, one of the most popular ultraportables on the market.
No installable RAM? The Sony TZ maxes out at 2GB of RAM anyway (and a TZ with 2GB RAM is extraordinarily expensive).

All well and good, but it changes nothing. Apple could have included an external DVD burner as some manufacturers do. Apple could have provided a BTO option for more RAM (as well as one for the 160 GB 1' drive that Samsung released a month ago and which inhabits the iPod Classic). Apple could have made the battery detachable so that those of us who are true road warriors could continue to use our laptops on long flights (my frequent run from SFO to Singapore is more than 12 hours and not every plane has seat-side power adaptors). Apple could quite easily have added a second USB port with an ethernet adaptor or a firewire port, which will also do networking (they didn't because they are trying to drive Airport sales, not because the customer doesn't want or need it. I defy anyone who works regularly in a corp environment to say they have no need of ethernet). Basically, Apple is designing its hardware to drive its own agenda, not the consumers. I really like Apple products and have five Apple computers between desktops and laptops, but lately Apple behavior towards its customers has been greedy and arrogant. Whether its stiffing early adopters of the iPhone, charging iTouch users for apps that clearly were compatible with and should have been included ion the original product, the omission of cabling and docking stations from its other iPods which it used to include, not 'fessing up promptly to design flaws in its computers (such as the defective displays in some of the Macbook Pros or quick-staining palm rests on its Macbook products), Apple appears to care more and more for its margins and less and less for its customers, you know the 9 to 5ers who work for a living and have to think twice or thrice before they drop a grand (or two or three) on a computer.
