Popularity list?
The list of cars most likely to be stolen in raw numbers are the most popular, like a Ford Focus. Thieves might rather steal a $80K Mercedes, but there are fewer of those so fewer will be stolen.
The same will be true for phones. No matter what Apple does with activation lock, the iPhone will probably top the list because a couple of models of iPhone will always top the sales lists for any given year. Samsung and other Android makers are spreading their sales amongst a much larger array of models, so any one will be well down the list.
What good is a list that reads like:
iPhone 5S
iPhone 5C
iPhone 5
Galaxy S5
Galaxy S4
Galaxy S3
Note 3
etc.?
Other than making Windows Phone and Blackberry owners feel unjustifiably smug in their purchase decisions, that is? :)
