Listen to yourself
"the need for 0-day patching is therefore not necessarily as great" are you out of your tree? Security in any aspect is PRIORITY any way you slice it. This "stigma" about MS being Krap only shows you Mac folks to watch your step.
The only reason MS gets more publicity in ref to Vunerabiliteis is because as a Hacker you want to be known as the person to beat up the toughest kid in school and MS is the biggest dog on the street. I too have had MS since the days of DOS and I know one thing it's a reliable OS- the primary reason there are problems with PC's w/ a MS OS is because to misuse and not enough dilligence in keeping up w/ Anti-virus & Maint. I am sure MAC has allot more than they let on. because when you add it up and compare there are allot more MS pc's than MAC's out there.
