>The Windows SDK today is still huge. The download for the Vista version is over a Gig...and that's compressed. I didn't install the whole thing so I can't say how big it expands, but my install is at 1.26 Gig.

When I remember that VAX OS documentation took only about 1.5 meters of shelf space (and that I actually had the time to read most of it)... and it was still something fitting one brain. With Windows, I doubt anyone knows everything.
