Actually, the iOS model isn't that great IMO. Rather than relying on verifiably safe bytecode, Apple uses a combination of TrustedBSD-based technology on the phone, and human-directed testing in their labs, in an attempt to keep native code from doing things they don't want it to. I think this is backwards for what they're trying to achieve, and I think that's part of the reason their app review process is such a pain in the ass.
