Intel's Visual Computing Group (VCG) has the mission to establish the future of computing for high-throughput workloads. We are focused on developing discrete graphics products based on a many-core architecture targeting high-end client platforms. Our vision is that the resulting ingredients and technology will extend to mobile clients, servers, and embedded platforms over time. VCG will initially focus on discrete graphics products but will also expand the previous charter to include developing plans for accelerated CPU integration.

It isn't Aero glass, per se, that doesn't function at its full capabilites, but rather the Desktop Window Manager engine (DWM).
This might not be exactly correct, it is just my best understanding of what's going on... if someone has better information, please enlighten us.
Basically, DirectX 9 cards can only process one graphical stream at a time. Since the Aero glass interface requires a constant stream of GPU acceleration, if something else that requires GPU horsepower is started on the system, Aero glass needs to shut down so that the other process can get access to the resources of the GPU. (and it does)
Most of the time you don't see this, because the majority of the things that require graphics acceleration are full screen games... there are a few things, though, that will revert Vista to the Windows Vista Basic theme.
For example, one of them is Java. If you want to check this out, install Sun's Java package (if you don't already have it.) and then load a webpage (any page) that has java embedded in it. Vista should revert to the Windows Vista Basic Theme until you close your internet browser. (I haven't actually done this with anything other than IE, but considering how the engine is supposed to work, I would assume that it's the same with Firefox, Opera, etc.)
Anyhow, DX10 allows for simultaneous processing of multiple graphics streams, allowing Vista to continue using the glass interface, while still giving the other process the resources it needs.
That's all it really is... I didn't mean to make it seem like a big deal. It's not... but there is a little bit more functionality that you get with a DX10 part over a DX9 one.
P.S. Forgive my incoherency... I'm extremely tired at the time of this post. Hopefully I got my point across.

Blythe: It continues to use DirectX 9. Largely the reason for that is when we built the desktop, that was being done concurrently with the design of DirectX 10. It becomes somewhat more complicated to build both the low-level technology and the thing on top of it, concurrently. It's better to sort of have a time gap between those. At the same time, we were making some minor tweaks to DirectX 9 to accommodate new features that were needed to do the desktop. For us, it's best to have one consistent platform. Even though we could imagine there being benefit to the desktop using DX10, it's better to do all the debugging and get it to work with DX9 and ship that. Then over time, as the hardware base builds up for DX10, by the time we do the next major release, we'd be looking at trying to move the entire desktop onto 10.
