podle MSFT je nejbezpecnejsi OS na planete Vista: "Vista today, post-Service Pack 2, which is now in the marketplace, is the safest, most reliable OS we've ever built. It's also the most secure OS on the planet, including Linux and open source and Apple Leopard. It's the safest and most secure OS on the planet today.", pravda nespecifikuje o jakou planetu se jedna

Dolezite je vsimnut si "which is now in the marketplace", cize volne prelozene "v predaji". Kedze si vsak OpenBSD (a ine ;-) ) mozeme stiahnut OFICIALNE zadarmo, tak Vista je asi najbezpecnejsia len v segmente "marketplace" :-))
