My thought is that there is value in a LiveCD which really is a CD, and value in 
a LiveDVD which puts virtually everything you normally want on one media, but 
there is little utility in an ISO which doesn't fit on a CD but still needs 
network connectivity to be really useful. I can appreciate some people wanting 
to use a 4GB USB, but 3.5GB of ISO leaves room for some work space and provides 
enough tools to be useful.

A benefit during rapid change (pre-beta) is that if you find that you need X you 
may have to upgrade a bunch of other things to get X, while X on the ISO may be 
obsolete, but at least it matches.

Yes, I know my opinion is not universally shared. ;-)
