Remember the comment is in respect to VLC and other CPU intensive apps or functions.

Most certainly! Much of that capability is due to hardware acceleration. Video playback of certain encodings works so well because of hardware acceleration. What I tried to point out is that apps demanding significant CPU power will not always meet peoples expectations because many optimizations make iPad appear faster than the CPU really is.
In this case VLC seems to have this issue. CODECs demanding strong CPU performance seem to have issues. The word "seem" is important here because VLC is very much a rev one software release. There could be potential for more aggressive optimization.
If not aspects of a device arent the fastest among all products does that mean its not fast in doing certain tasks? Is it fair to only judge speed by the power of the CPU when its the users ability to complete a task that really matters?
Well this was a discussion about VLC not completing a task or displaying degraded performance.
Outside of VLC how the task is completed can be important too. Fortunately the types of apps popular on iPad have been doing very well on the device. That is in part due to developers realizing the limits of the device.
If we were comparing the same OS to the vastly different CPUs then it would be a clear win for the faster CPU if the task was CPU intensive, but were not as Apple clearly redesigned OS X to be idealized for three different ARM-based products each with different UIs, two using CocoaTouch for the I/O.
The OS doesn't matter. Rather it is app performance that matters. To me it is no surprise that Apple kept apps like VLC off the platform for as long as they did as slow apps could have given the platform a poor rep before establishing itself. At this point people have a better idea of what to expect.
1) Ive never seen CF on a computer be functional. I have a very limited knowledge of CF but they all seemed to be flimsy, not rigid, which is something I dont want to see in a case for rigid components inside.
While I'm not a fan of carbon fiber, I do have to point out that structures made with the stuff can be very ridged. The problem for Apple is that they can't easily do a unibody with the machined in features.
Ive seen CF that was very rigid so perhaps there is a minimum thickness that needs to be employed but isnt for some reason.
It is likely more an issue of engineering though thicknees plays a part. The problem is well engineered carbon fiber parts are expensive and not exactly mass production items. It is sort of like hand laid up fiberglass/carbon boats which can be very nice indeed but expensive to make.
2) I think Apples employing aluminium in so many of their consumer products doesnt get enough attention. From the two pieces of the iPhone frame being milled at 1 million(?) per week and growing to the new Mac mini being a solid block of aluminum when the product category wont have the same wear and tear and size requirement as the average notebook is simply amazing. I hope one day we get some detail into how they were able to accomplish this.
This also points out just how cheap labor is in China. When the first Unibody MBP where rumored I couldn't believe that they would be cost effective. Sure the idea sounds grand but looking at from the stand point of a person in the US it is hard to believe that they could CNC each and everyone of those cases. The cost "should" be huge, but obviously Apple is still shipping products that are bearable cost wise.
So yeah pretty amazing. The Liquid Metals licenses though seems to indicate that they need lower cost alternatives that keep quality high. I suspect that this material could see first application in a iPad rev. The reason being the back is about the right size to make usage of an injection molding process practicle. The only other approach, for thin cross sections, is blow molding which I find very strange when talking about metals.
All in all We should be seeing some very interesting ideas with respect to cases and chassis design from Apple soon.
