Does the Windows version of iTunes work as seamlessly/well as the OS X version for Airplay, sharing, etc.?
I don't have a Mac so I don't really have any points of comparison. What I do know is that iTunes works better on any Windows computer I've owned better than Windows Media Player, and is why I switched back to an iPhone ~2 years ago from Android. But yeah, in the past there were issues with performance on Windows machines, back when PCs maxed out their RAM at just under 4GB because of the 32bit architecture of the OS and most only came with 2GB of RAM. Considering that my six year old desktop, which when new was mid-range came with 8... not really an issue anymore.
I have not tried streaming from iTunes to more than one other device at a time, it's just me here.
