It's difficult to find things you want. Application paradigm is broken down and it's incompatible with previous model. What was a nested directory is suddenly a flat list, with even all the unessential help text files. The new "apps" are completely worthless and have a very poor performance. It seems to me that Windows Search doesn't work half the time. With Windows 7 it worked all the time. There's so much useless things that I have no use for that only clutter the interface unnecessarily. It's very schizophrenic. Context switching is a very expensive operation for the human mind. Doing it for absolutely no reason what so ever is extremely annoying.
