Is there anyone that has upgraded there PPC running OS 10.3.9 to 10.5? If so what were your problems? I am specifically worried about mail. Did anyone loose there messages during the upgrade? How about bookmarks? Or any major files? Would you do it again or wait until all the bugs are worked out? My main reason for upgrade is to take advantage of time machine. Other than that I am happy with 10.3.9. Please let me know. Thank to all.
