what's the problem of CLOSING a Metro app
All you have to do is point your mouse (I'm not using touch screens) at the TOP LEFT hand edge of the screen when you are in the Metro app. You'll see a little image of the desktop app -- click on that to get back to the desktop. Again point mouse to the TOP LEFT hand edge again and you'll see a little image of the Metro app. Right mouse click on it and select close.
Most of the complaints about Metro (other thgan the "De-Uglification" process are made by people who seemingly haven't understood the Navigation system. Just think of the Corners of the screen as "The 4 Horsemen of the Apocolypse". !! moving the mouse to any of these corners whether in the desktop or not and "All shall be revealed".
Most stuff is quite accessible -- For example I have No probs accessing control panel via the Charms setting ==>settings and choosing the top entry -- much more logical than having to grab this from a "Classical Start" menu with loads of Non system type applications on it.
(Whoever dreamt up that ridiculous name "Charms" BTW ??). They must have been smoking that funny smelling tobacco available in Amsterdam's famous "Coffee Shops") .
Or, even simpler, just press Alt-F4, and hey presto, App is gone. Damn, now I've said that, MS will probably go and disable the Alt-F4 shortcut, just to prevent me even *wanting* to close an App.
BTW, one good reason for closing them is that it reduces clutter in the Alt-Tab list. I use that all the time to switch between open programmes (including Apps), and the more redundant ones are open, the more I have to keep tabbing through the list to get to the one I want.
Little does M$ realize that putting window controls on the top right corner of their Metro apps gives those Metro apps a usability and navigation advantage over apps of Androids or iPads because its so much more obvious on how to switch in between and close apps. I suggest you read this article:
Windows 8 Metro Apps Need Close Buttons Too - Softpedia
didn't you read at least 2 Posts on saying how to close Metro apps -- you DON'T have to drag them anywhere --- and it's no different in fact to performing the close or exit function from a normal application such as Photoshop.
As for difficulty in adjusting -- took me about 10 mins -- and I'm not YOUNG any more.
No Dragging / dropping required
and in fact it's actually MORE efficient than say having several Windows (normal) applications running and just having them minimized as they are totally swapped out when not being used. This is one reason that W8 can perform SIGNIFICANTLY better than W7 when you use something like an SSD as swapping the app in will take almost no time at all.
The Metro idea can use system resources MUCH MORE EFFICIENTLY.
Before quoting stuff available all over the Net have a quick read of how basic Operating systems work --in particular how the Task Manager and Dispatcher functions operate -- the basic principles are followed by most OS'es.
I wouldn't rely on getting my info from places such as Softpaedia -- they aren't set up as educational establishments --downloading Software from them is another matter -- that's quite OK.
Where I *could* possibly agree is that as it's laid out at the moment it is either difficult or impossible to run Metro Apps in anything other than full screen mode - which makes using multi-monitors with "extendable desktops" not very possible or the possibility (often wanted in commercial world) of running appplications so you can compare for example two or 3 web sites, excel spread sheets or just display a set of different documents side by side say a PDF, a Word and a Powerpoint document. (Ms office apps can of course currently -- but when these apps appear in Metro Mode will it be possible then -- WITHOUT USING THE DESKTOP) !!.
And another thing I don't like is that some defenders of the Metro like you, seems to insist that the current design of these Metro apps, regardless if they have a close button and window controls are seemingly flawless just because you haven't had a significant difficulty adjusting yourself on the way that works right now. But understand that others (including some power users) simply don't view it that way and just because they don't doesn't mean they are wrong. Same as the Start button that M$ removed on the CP. What harm does leaving the Start button alone on the Taskbar do? In fact nothing, except you got room for 1 more pinned icon on the Taskbar when the Start button is gone. For me, removing it became a burden especially to many less computer literate. M$ just isn't that open minded as it stands now.
How is that easier than just closing it?
"People are re-enabling the "Start Menu. We'd better eliminate the Reg hack."
"People are shutting down apps. We'd better eliminate Alt + F4."
"You worthless peasants will use the system the way we want you to use it."
No worry in few months after they will realize Windows 8 is a fail, and more and more peoples continue to prefer Android phones, Microsoft will have no choice to listen what their customers request. I hate Android phones, but from what I see it's better than what Microsoft will offer.
Plus, you use the same movement (Drag down half way and then left or right) to move the app into snap view so you can decide to close an app, then change your mind and do any other productivity stuff, leaving the app in snap. I do this all the time (quite absentmindedly). It's like riding a bicycle after the first day or so.
For me, the fewer little buttons I have to click, the better.
