And I answered it honestly. You proposed a flawed premise (lack of updates for Android phones) and I corrected you. It sounds like your coworker is misinformed about the nature of Android updates and I gave you information to correct him. Maybe he would appreciate that he can update his apps with granularity, instead of once a year. Maybe you should be "honest" with him and point out that the specific advantage Android has when it can update its apps independent of OS version.
