I wasn't very impressed with this software but keep it around in case it gets better. I just fired it up today and noticed that there was an update to 1.00.25. I installed it thinking it might get better in some way but it still looks the same. BTW, this installed flawlessly on my Vista x64 machine.
My favorite sync tool for music is a toss up between doubleTwist and Songbird. DoubleTwist goes the extra mile with video conversion and photo sync and every update of it makes it better and better. I'm torn between Songbird which is a killer player for the PC and doubleTwist which offers the "complete" experience similar to what iTunes does.
I still say the ultimate would be a PC/Droid application package that works together. Full featured PC app to sync and a killer media player to compliment it on the Android OS. I'd pay $30 - $50 for this and can't believe devs haven't picked up on this NEED!
