All people are used to close or get rid of an application by using the X button so its very
substantial for users even if that button does not close but suspend the application but its very important
another thing that i noticed is a lot of graphical glitches starting from the unlock screen . when i am unlocking there is a big black square appear ender the unlock the disappear . and some of metro apps conflict some how with the metro itself i will try
to record and video and show you the details as soon as possible .
My 1st care is best windows 8 that makes all people try , enjoy , and have good time using their new windows 8 version ! :D
The exit button, traditionally, is the responsibility of the author of full screen apps. You don't see a Windows exit button on top right in full screen games.
