I've never had much luck with " suites" either. If you try to be too many things to too many people, something always seems to suffer. Dividing and conquering with specialized products seems the best idea to me. But, most people are not that computer savvy, so there will always be a market for the all-in-one packages, I suppose.
MS's Live OneCare, and the others that are coming to market with an overall service to care for a computer, for the casual user that is aware of viruses, spyware, etc., but doesn't have time or inclination to learn, is probably going to be really popular. And probably a good thing too, since anything is better than nothing.
By the way, I grant to all, that a small amount of users complain in forums. But, from a statistical sampling view (which works a little like political polls), the wide variety of issues complained about on ZA's forum, and other forums, if you take the time to search, is disturbing, and most frequently are about ZA's "value added" programs, and not the free version of their firewall.
