Actually the idea is interesting, but:

1) the overhead for the network part can be higher when we speak of gigabit 
ethernet - even with the best server cards (over 3-400 US$ each);

2) since on the motherboard you will still have 1 network card you will not 
have "1 gigabit each", you will mostly have "1 gigabit shared" (since transfers 
will not be done "device to device" but instead "device to host to device";

3) the complexity would be higher - and a lot of "translation protocols" that 
barely work over USB or 1394 would have to be again changed.

Actually on an older G3 notebook I also saw that some other keys are missing, 
like for instance PgUp/PgDown ...

There are MANY other drawbacks, and even if some people might initially think 
that somethink like that is better I am afraid that is only true for rather 
simple situations ...

Also the speed is probably related more to the very limited hardware 
configuration - the Mini is a notebook-class device rather than a desktop-class 
machine, and on top of that the Apple notebook class is currently quite "dated" 
from the hardware point of view when compared with "modern" x86 notebook PCs 
...

I am very tempted to create a small utility for Macs to do just that :) :) :)

There are some other things missing - for instance the -related menu 
navigation from Windows - and I am tempted to take a look at that too in my 
small utility :)

What else is missing in the Mac world - please let me know ! :)

I am not convinced (at all!) that full screen is such a bad thing...

Well, my feeling is that Apple is a far worse "monopolist" than Microsoft, and 
on top of that the lack of spyware/viruses can only be short-lived ...

But anyway if you want to buy a Mac notebook I would suggest to wait at least 
one month more, or ideally until the next OS X is released!
