the only thing i can think of that would get me to switch to ios over android would be if they came out of the box with the ability to sideload apps without jailbreaking
It has this. Just enroll the device as a developer device, and compile the code, or enroll it as a corporate device, if you want to use precompiled code you trust but that Apple won't allow into the App store because Apple doesn't trust it.
If you mean thing like side-loading just random crap, like if I were a private detective hired by your wife, and had 60 seconds of access to your iPhone, I could sideload some serious backdoor onto your phone to enable me to monitor your texts, phone calls, email, Facebook, and so on
