Irrespective of whether Windows 8 improves or hampers productivity, I get the impression here that there a lot of the computer users who have everything arranged very specifically in their current operating system and would take issue with any change in their workflow, even if it would have no effect on productivity after he or she got used to it. This is really the same as the Mac OS vs Windows argument; experienced users of each OS can do the same things in the same amount of time (games being the only real exception) but the methods to complete tasks are different and are largely not transferable. This makes any users who try to switch complain the alternative is not intuitive when in reality they are approaching the new OS with preconceptions that cloud their experience. As far as my experience with Windows 8, I am very happy due to the minor tweaks added (improved copy dialog, Hyper-V, improved task manager, multiple desktop taskbars ala UltraMon) and the increased focus on search (for example the new Start menu). Whether people like it or not, search is the future and folder tree structures are the past. We are getting to the point where computers will manage everything in our lives, and that means there will an ever increasing number of applications and files on them. Folder trees just become inefficient after a certain number of objects are stored, and the new Start menu is just another transition to a search-based UI. When you think of a keyboard as a mouse with a hundred buttons, you begin to realize the power of using the keyboard to search rather than the two button mouse to point and click a folder tree.
