Digital BW, The Print

hi all-

i searched the archives and couldn't find any advice. i am currently 
running mis-fsn inks in an 1160 using the piezography plug-in on 
powerbook g4 - i also use a polaroid 120 scanner and an epson 2450 for 
my 4x5 negs. i was thinking of finally upgrading to mac os x. has any 
one using a similar set-up upgraded yet? does the piezo plug in still 
work - what about the scanners?

thanks
Mike Bragg
