Remember: app curation by Apple isn't driven by any kind of instrumentation and doesn't prevent malware until after it becomes well known. There is no advantage it gives to consumers, it just prevents apps from taking users from Apple's services.

That is: the iphone app store doesn't improve upon the OSX security situation.

Also, at least the commador64 had publicly available schematics (I think they may have been included with the machine.) The only modern phone doing this that I'm aware of is the PinePhone.
