Device tags on power meter

Kinda speaks to the long-term possibility for more UI optimization to reduce the (Sense-local) processor load. Would switching off the delta tags and device labeling in the Power Meter reduce load enough to bother? Should we have a toggle for that? What is the real-world correlation between potential data dropouts (Priority #1 to be avoided) vs. UI bells and whistles (lower priority)?

Some kind of quantification along these lines would be great @RyanAtSense.
