Michael Tsai:

I never liked how the estimate claimed to be accurate down to the minute. I would like to see an estimate with fewer significant digits, both to hide the erratic changes and to avoid over-representing the accuracy.

This would be a much more elegant solution to the problem rather than removing the indicator all together. Saying something like “About 4 Hours Remaining” would give you most of the information you needed without making you feel like the estimation is gospel.
