A delta update for Xcode would be a nightmare for both us and the Xcode team
if you think about it.

Could someone please explain the reasoning behind this.

In an attempt to restore the topic of this thread:

The Xcode 1.1 delta was a nightmare because it was incomplete, and I think that was intentional in order to bring down download sizes. In the end, it was missing a newer version of Interface Builder that didn't clobber .svn directories inside nibs, as well as a new and not 100% backward-compatible 10.2.8 SDK (the SDK that shipped with Xcode 1.0 was a "10.2.7" SDK, so everyone who installed the delta still had that one installed). Of course, if you're a lone developer and don't use Subversion, then those two things don't matter that much. But these two things, and in particular the SDK issue, made working on distributed projects a nightmare because everyone had different versions of 1.1 installed. Go search the list archives if you don't believe me...

Anyway, a delta would make sense if they included every single file that was updated, which is a tricky thing to do since a single difference in a file between the "delta" and "full" installs can cause chaos in distributed projects. In the end, since every file usually gets updated anyway, it's probably best that things stay the way they are.
