Wow, its been such a long time since I've been back in this forum. I've got myself a Macbook Pro and an iPhone and was stuck with iTunes for a long time but recently, I've gotten myself an Android phone and decided to try using JRiver Media Center in Parallels. I've to say, I've no idea how much I missed JRiver Media Center until I start to use it to manage my music again! Even in Parallels, it is faster than iTunes!
Just have to add, since 15, 16 has definitely quite a huge performance increase and everything runs so smoothly even in Parallels. Using Media Center in Coherence with Noire Glass skin is just such a treat.
