From an administrative perspective I think it's a very good way to save space. Remember years ago when people installed windows applications, and the DLLs clobbered each other and broke everything?
Now they can follow a sensible standard: the application's DLLs are installed alongside the application and the filesystem removes duplication automatically.
I suppose the installer could do that, if everyone agrees to use the same installer.
Do you think this doesn't happen with unix? It certainly does in large multiuser installations. Users download, build and install their own local copies of various software. Because they're not root. Because their bit of extra software shouldn't interfere with the "standard" set of software managed by the sysadmins.
That causes duplicated files. Even a tool that finds duplicate files and hard links them is no good for that situation -- each user requires the view that the files are their own.
