Office for four years prices not too expensive ... I bought it for my office documents on my Android phone for synchronization with Skydrive (ondrive) does not interest me. No surprise, Office on two PCs and two phones or tablets (Excel, Word ...). But I finally uses QuickOffice (Google Office) on my Android phone, in short a purchase for anything. Otherwise Galley Maid Version, few changes ... And activation of the student version is very tedious, impossible with the single procedure online, call Microsoft and be patient to activate the product.
