The issues are most likely to appear with users who go straight from Windows XP to 8. They are not familiar with the ability to search among applications and files, nor with the concept of pinning shortcuts to the taskbar.

Considering the marketshare XP still has, and that these users are likely the ones most resistant to change, this may turn out to be one of the largest problems Microsoft will face with Windows 8.

I am not saying that legacy-concepts should delay innovation, but it can't be denied that Windows has many users who aren't interested in learning new ways to work with their computer.
