He doesn't even know what he's talking about. Did this guy poke around AT ALL in Windows 8?
"If you want to start Steam, youâ€™ll want to launch the Desktop app, and then launch Steam."
You do NOT have to go back to the regular desktop to launch an app.
1) There are tile for your apps on the Metro desktop. You can unpin any you don't want there and you can rearrange them however you want.
2) If you right click on a blank area of the Metro desktop a bar appears at the bottom of the screen that says "all apps" Click this and all of your apps are listed on tiles in alphabetical order. All with out leaving the Metro interface.
"thereâ€™s no on-screen preview of whatâ€™s running to help you quickly switch between programs."
Yes there is. Move your mouse to the top left hand side of the screen and a tile showing where you were before will drop down. Move your mouse down a little and a list of open apps will drop down.
I found all of this just buy experimenting. This guy didn't even try to find out how the OS works. He hated Metro and because of this he didn't even TRY to give the OS half a chance. Seriously biased article. Seriously biased writer.
I do agree however that the Calendar Photo Music and Video apps are terrible
