I'm interested in this as well. There is anecdotal evidence that allowing side loading and 3rd party app stores makes the ecosystem less secure and makes it more difficult to respond to threats (volume of android infections vs. iOS, as well as case-by-case analysis of specific malware that is done by security companies), but I've never seen a more comprehensive review of HOW malware gets installed on devices (vectors), to be able to quantify the impact of closed vs. open app loading. Anyone seen an actual decent review of this?
