Despite ill omens, the IDC report about PC volume decline hitting -14% in the first quarter shows once again how much trouble the tech industry is having when it comes to dealing with the ongoing computer meltdown. As I wrote last December, IDC has been completely out to lunch about this key trend for years. In March of 2012, IDC was still expecting “desktop and laptop sales to take off in the second half of 2012.” Last December, IDC cheerfully predicted 1.2% growth in computer sales between 2012 and 2016. Of course, the PC industry is tucking into a majestic swan dive that makes those projections downright surreal. How can one of the most respected research firms in the computer sector be so disconnected from reality? The answer is simple: Analysts from largest research firms simply aren’t allowed to call major turning points.
