It was that way since the beginning. The Sony TZ was around 2 pounds and it still had an optical drive in it and two USB ports and even a built in broadband card.
Now Sony offers it with an external optical drive and BOTH a SSD and 1.8" HDD. Something I may do with my 17" since I don't burn much.
It's by far the best laptop I have seen on the market for portability and functionality. And after using it for a while it's still quite easy to type on at 11.1"
Please don't compare 11.1" to 13.3". There're many people out there who wouldn't be fine with as small a screen as you are happy with. My favorite thing about Air is that it has the best proportion of screen size to weight, as far as I know. For you definition of "ultra-portable" might be small size and low weight. For some people it's just size. For me it's weight that makes it. Air is barely bigger than A4 format.
If we take a look at 13.3" computers with similar weight, there're a few conclusions:
1. Most of them have removable optical drive - meaning: they're heavier when you put it in, but they're always advertised with the lowest weight for obvious reasons, so it's practically the same as if they given you an external drive (just substract $99 from the price of the laptop and you can compare to the Air);
2. Most of them don't have better battery life - again, usually the values given show the maximum time you can get with additional battery, but without the weight of this battery (consider the basic option and the time it gives you, then compare to the Air);
3. When you choose options making them similar to the Air (LED, SSD, equivalent CPU and RAM), substract $99 if the CD/DVD drive is attached and go on with basic battery, you find out that most of them are also more expensive.
The Air is still a great option, and in typical Apple fashion it is behind the curve, (buy refurbished for $1500) but still worth the price with a good deal.
The next iteration may just have the atom and a bigger hard drive along with NO bugs, but I doubt much on connectivity will change. Especially since it was really meant to be a wireless machine. Personally, they can take the USB port off and I'd be happy.
Well, I hope there'll be a good CPU there and more SSD options
