I have so far started to use the Thinkcentre windows side to sync my Blackberry. Now I will also use it for iTunes and the Wireless Music Bridge. Since I have started to use iTunes on Windows I have had nothing but headaches loading all my music. This past hour I decided to delete everything on that iTunes.
I am also backing up my eMac iTunes to some 4.7 GB DVD's but this has been headache prone too. Right now I am starting again; having ruined three DVD's trying. First, I am downloading a bunch of podcasts. When those are updated, I will back up the iTunes on the eMac.
I also have been using iTunes on the IBM to get my songs from the library of music to my Blackberry. This was the initial reason to put iTunes there. This worked but the Blackberry is troublesome for listening to music while traveling around on the bus. It turns off and on and stuff. I have still have not learned all the buttons or the lock screen function beyond using it once only.
