I agree, and like I said when released I will most likely be running Windows 8 at some point, though you didn't have to learn hardly anything even coming from XP - Vista - Win7, there are things to learn if you want to though on the whole everything is centred around your start button/menu. It's not in Windows 8, there is more to do (essentially more mouse clicks) to perform simple tasks that could all be done in one click in Windows 7, I had to constantly switch between metro and the desktop to perform some actions, there may well be an easier method to perform these but it's actively having to find out what these are, Windows Vista/7 was as easy to use as XP from day one, I would say if anything I learnt more about them the longer I ran them.
BTW I haven't stated I don't like it, though the reasons I listed are what I have experienced whilst using it and also what I seem to get from the people who don't like it.
It is easier for the average joe to use as they only have the one screen with everything they do on their PC right there, they have no need to go into explorer/control panel etc most of the time anyway, generally I would say it's people like the people on here who know how to install, maintain, troubleshoot etc who find it frustrating as doing these things is more laborious and not very "clean" or intuitive. Kind of ironic if you ask me... lol
In short, no start menu and metro is why it's shit lol
