Do you have more information on Apple's security track-record? Seems to me to be much better than Microsoft or Android.
No, this is not true. Two main notes:
1) The only reason people hear about Android "malware" is because antivirus companies are allowed to provide antivirus software for Android. Rarely do they mention that it's people downloading pirated apps from shady third party app stores after they've disabled all the security features.
2) All those "jailbreaks" for iPhones? Those are ALL security exploits. If they can be used to jailbreak the phone, they can be (and have been) used to completely pwn the phone.
