What kind of app would you like to use? There are quite a few apps now that can use the vga out. Pages works well for PowerPoint slides. For particular categories of apps maybe we can suggest ones that would work.
Maybe we should start a new list:

As an iOS developer I can tell you exactly what is happening.
First off, I was surprised as well when I purchased my VGA adapter for iPad. One of my clients was about to do a real-estate TradeShow where we developed their app and they wanted it to be available on a large screen output. It did not work as anticipated...
So after digging into docs, it became clear that each app needs to be custom developed to support the VGA output. A secondary 'screen' device has to be created (programmatically) and the graphics output needs to be drawn to this VGA screen. But doing so makes the iPad screen go dark - so in the end the solution is to copy the contents (as many frames per second as the app can tolerate) from the primary iPad screen to the VGA output screen (and resized as required).
I've done this option for various clients since, but it is not an elegant solution since the graphic animations can be sometimes choppy.
Apple SDK in fact makes even this difficult since they BAN apps which use their own internal API to do this efficiently (since last July 2010).
This is why only some apps support VGA output.
From a developer perspective, this was a surprise. This should be available as base iOS capability at the core level. I guess this is another case of 'performance' issue like flash.
My feeling is that this will be corrected in future iPad release.
Sometimes the Apple support/sales people are Apple's worse enemies. There are many functions that are better served with a laptop, and if it is a hassle to do it on an iPad, they should put that out to customers. I would never give up my iPad, but a lot of times my MBP also travels with me. A motorcycle is great, but does not replace a car.
Thanks, I think that it must be an oversight too. I am looking forward to seeing it fixed. What I would REALLY like to see is the ability to "throw" the iPad screen to TV via AppleTV.
