I was an iphone girl for 4 years until last week when I traded it in for an HTC sensation. I love it except for the difficulty it has caused me syncing my music and playlists from my mac. I have tried doubletwist, isync, mediamonkey, Salling media sync, songbird, and a few others. The issue is that most of these programs require OS 10.5+ while I unfortunately have OS 10.4. As it is very expensive to upgrade to OS 10.5, is there anyone who can help me find a good syncing program that works for me? I now find myself missing my iphone!!
