Looking for References

Have any of you, my educated and intelligent friends, family and others, come across any comments (preferably thoughtful and insightful) on Umberto Eco's IBM vs. Mac blurby? I'm going to be writing an essay on it and, while the excerpt itself is all over the web, there aren't too many useful comments (at least, I coudn't find many, but then I only spent an hour or so looking). Obviously, most of the essay will be my own thoughts about what he meant, etc, but it woud be nice to have a few outside sources. Print sources are good, too (Niko like library).
