I was going to answer the exact same thing. I loved serving on it, but it was all but unplayable.
I've played on the astroturf, and honestly it didn't bother me.
The most painful experience was a concrete court w/ no asphalt layer. I've never had knee problems, but they were both barking after that weekend (3 tournament matches). You wouldn't think that asphalt is that much of a cushion until you play on concrete. Never again.
