For what it's worth, iTunes is much less awful on a OSX. Also, Office 2011 for Mac is pretty fantastic. I can finally do all of my work on my MacBook without having to dual boot Windows, and I haven't had any compatibility issues with people running Office 2010. The only thing that Mac is still awful for is gaming, but even that seems to be changing.
I haven't heard anything good about Flash on Android. I think it's unfortunate that Google latched onto that as a selling point, it would have been nice if all of the major players withdrew support from Flash so that content providers would start moving towards HTML 5. Flash is a buggy, insecure, bloated, battery-hogging mess, and it needs to be put down. These days it seems like I update it more often than I use it.
