From a repairability point of view, Appple kit is awful. it looks pretty, but try taking it apart to replace a failed drive. For instance a Mac Mini has to be assaulted with pallette knives to safely open it. As as for a unibody.....aaargh
And what I really object to is the way in which apple insists on total control
On an ipad or iphone you can only install apps from people it likes,
And everytime you buy a book or newspaper or other media online - 40% or more of the cost goes to Apple. That doesn't happen with M$
