If you've been following the tech news, you may have heard that Apple announced iTunes for Mac will be split into three separate apps: Music, Podcasts, and TV. (See details at Engadget.) As far as I know, nothing has been announced yet about what will happen to iTunes for Windows. However, I wouldn't be surprised if the Windows version is eventually split as well.
IF iTunes for Windows is split, using Garmin Express to sync music and podcasts on a Windows platform could become even more difficult. The Windows users among us with our iTunes libraries on D:\ instead of C:\ already know that syncing music via Garmin Express can be clunky. If we find ourselves with different apps to sync music and podcasts, the sync process could get even more difficult.
I'll be watching the tech sites for any news about the fate of iTunes for Windows!
