True. I will agree with the price thing. I am not saying to make this stuff standard. But a cap on Ram is really crappy. The power of the machine isn't that great, considering that there exist faster processors with more cores. The LED thing would cost similar to what they do now.
The flash type memory is cheap. Its essentially the same as a memory stick - so since i just bought a 4GB for 17$, popping four of those inside wouldn't cost all that much more. If you wanted to go up to 64gb, then you are right.
I would pay more to have my OS run even faster. You are talking about running at speeds that are not limited by the access time of a spinning disk. You could technically run at the speed of the bus, which is another thing that could use a little kick.
Personally, I have the newest model of the 17" macbook pro. Ive been using macs for the past 5 years of my life, always in the pro lines. This one is by far the most powerful machine i have ever used. However, I still notice a small lag when I am really giving it to the computer. I would like this to go away.
