I gave my husband an iPad, but I am the navigator. So when he gets stuck we need to figure it out. I have a Mac so it works well together. He is still on a PC. We travel a lot and he finds the iPad great and doesn't need his PC at all. So now I am trying to figure out why there is black line under Skype and iBook and the message says "Unable to Download." I will try to find the correct Forum to ask. I have been reading the other posts and finding them interesting as well.
