Vista - Ultimate Extras

Ultimate Extras... people purchased Vista Ultimate to get these so called "extras". Actually they got next to nothing. The most Extra I've used is the Hold 'Em game. $200 is a bit of a high price to pay for one game...
ZDNet have a nice blog entry about it:

Vista SP1 “tries to hide the Ultimate Extras shame” by ZDNet's Adrian Kingsley-Hughes -- While many are waiting on Windows Vista SP1 to come along to knock off some of Vista's rough corners, it seems that some at Microsoft will welcome the release too - specifically Microsoft’s Windows Ultimate group.

The one Extra I don't get is DreamScene. For those of you who haven't seen it, DreamScene is actually a looping video background for the desktop. So you get a running waterfall, or flowers moving in the wind, all this on your desktop.
Can anyone tell me what's the deal with this? Who's sitting watching the background move? All this also has the price of CPU cycles and memory. This is one expensive extra.
