I do not mind either as an occasional change of pace (emphasis on occasional). With Azed's PDs, I just take the tack that this is not a cryptic crossword, but something else, and forge ahead (which I did with no real issues this week, jono, just FYI :). Perhaps as an American I have the advantage that I regularly work all sorts of non-cryptic puzzles, and this is just one more in that category.
As for Playfairs, I just cheat and use the online keyword crackers and encrypt/decrypt sites that are out there on the interwebs (hangs head in shame).
