Measuring Open Rates by mobile device

[Jamie_Barclay]

I'm looking to identify the opens via (any) mobile device so I can define a ratio of opens via mobile vs. overall opens.

Can you tell me if by adding the "Is Mobile Device" will capture all opens via a mobile device or do I need to drill down further?

I ran across this article:

I think that "Is Mobile Device" will give you slightly higher numbers than the suggestion in the thread you referenced. But, I think that either should give you pretty good metrics.
