I've been thinking a lot recently about open vs closed and I think it basically comes down to this:<p>Closed
- Users have more security (ex: recent reports state that Android users are being infected by trojans disguised fake Instagram apps)<p>link: http://www.theregister.co.uk/2012/04/19/instagram_android_sms_trojan/<p>BUT developers can spend months building something essentially inside Apple's jail (and then we are still faced with the approval process)<p>Open
- Users can install any application they want, and apps have the ability to access the device's file structure, etc.<p>- Large amount of non-curated, unfiltered content
- Higher potential for social engineering attacks to get bad code on people's devices
