Universal Binaries of DEVONagent, DEVONthink, DEVONnote, PhotoStickies and all freeware applications & services are now running fine over here - if anyone is interested in testing the Intel versions, just let me know!
By the way, the performance of DEVONthink on Core Duo machines is really impressive and up to twice as high as on a Dual-G5 computers running at the same clockspeed. So everybody upgrading from a PowerBook G4 to a MacBook Pro should be really satisfied with the overall performance
