I think the key there is the phrase "ease of attack".  Combined with a
poor patching stradgy on the part of the vendor who only bandaids the
issues <how many outlook/IE problems have to muster in before the core
issues are fixed?  Hom many times must DCOM and/or RPC be attacked before
the issue is fixed at the core of the problem?  shatter bugs in key
apps...>
