Computers are getting more and more indispensable nowadays. And aren't you bothered by Wind*ws? I often remember those old days (I was solely using an A2000/030/OS2.x during the years 1993-1999) when there was less to click, but more was getting done. A perfect OS needs to have a reasonable file system and easy-to-use shell (so why do I have to store my personal files anywhere at "C:\Documents and Settings\MyName\My Files" ??). Linux may also be confusing. And remember all those users whose PCs get more and more slowly just because of vast numbers of tools running minimized at system tray. I don't need thousands of buttons and menus to get my job done, as all these result in confusion. I believe that one day Easiness in Operating Systems will win, so we can all go back to work using PCs instead of working on their problems. So, OS4 may have a chance. There is a noticeable stem of users, and even though it still looks like a niche product, one day it could teach us a new kind of freedom.
