I should say that I would play, but only with a second copy. But this maybe doesn't say as much about the edition as about me - since I also have two copies of the normal, core 3.5 books, one for play and one to keep pristine. I'm funny that way. (But I don't do that with any of my other books - just the three core. Then again, those are the ones likely to get the most use anyway - especially the PHB - I ended up with four copies of the 3.0E PHB, and two of them are terribly beat up now, though at least one of those was loaned out a lot).
