I certainly may be wrong
I see the hottest IT 2012 trend as the destabilization of IT.
The second hottest IT 2012 trend is to wait for Windows 8 and Surface.
And maybe the third trend is to work toward HTML5 and CSS3 in the hope that customers will go upscale with their browsers.
That is an abosultely, positive, definite maybe in all categories.
Meanwhile, the hottest Management 2012 trend is the delusional belief that IT can run itself, go away and bring new and exciting possibilities all at the same time.
