The Metro UI is a step in the future, as it is very suited for touch screens, be it on a tablet or a pc. It does need a bit more tinkering with and more settings menus, to be able to get it better customized but it does look nice and usable. In it's current stage it's not yet ready to replace the classic desktop, but with a proper setting panel added, or a more thorough control panel for the metro ui, it would work out fine. In it's current stage though it's perfect for a tablet. And the desktop is still usable btw, as it is an integral part of the os still. As for linux, I disagree. It's way too easy to correct an issue in Linux and there is no need to re-install the os. Just need to know some commands to use in a text-mode. Linux doesn't get bugged down in time with usage, and also the file system is much better conceived with journalizing and easy recovery. If it had more support from developers, in terms of drivers, and games it would be as good if not better than windows. As a hint, if you tinker with the settings in linux, and you get an error or something, delete the .config files in the home directory and reboot. The system will recreate the standard .config files and revert all settings to default.
And on Windows 7,Windows XP and the other versions of windows,you have a start menu. And on Windows 7 and Windows Vista you have got a search bar which is even better.
But on Windows 8 Consumer Preview you have got nothing. And there was not even a search bar in Windows 8 CP like there is in Windows 7.It was just impossible to use.
And then there is the problem with Windows Explorer. That freezes your mouse so you cannot send shortcuts to your desktop.The ribbon toolbar seemed to be the cause of that. Andrea Borman.
