Apple is very, very lucky

Patching 2 vulns in Safari, 2 in WebKit and 2 in OSX? Sounds like the only reason Mac users are allowed to be smug about the paucity of invasions has been a string of good luck. The popularity (if you can call it that) of the iPhone will surely turn some nasty attention their way, and soon they may find themselves scrambling to keep up with the flood, as MS customers do. Security through arrogant obscurity is no way to protect your userbase.
