We changed the default from imshow to pcolormesh in #608. I would not be opposed to changing the default back, given that we already product essentially equivalent plots with both methods. We did add a performance note to our (currently broken) docs: http://xray.readthedocs.org/en/latest/plotting.html#two-dimensions

@jhamman and/or @clarkfitzg  may have some opinions here.

Does setting that manually make a difference? e.g., `t2_avg.plot.imshow`?
