Windows 8 Folders
With Windows 8 I believe you tried to get a one size fits all product out too fast. There are things that instead of enhancing user experience, they degrade it.
One example is the Start screen. As you can see there is a bunch of crap that I don’t (nor will ever) use. Please bring in the capability to add folders.
This would have been prevented if you learned from experience. The only thing you needed is one of the people that worked in the design team to be an iPhone user. Remember how the initial versions of iPhone did not have folders and they later added this functionality? Well, just do the same.
