The pace of the evolution of technology in IT keeps accelerating. The first notebook PCs I saw had lead-acid batteries, were thick and heavy and cost a premium over desktop PCs. It took more than a decade for notebooks to slim down and get close to being portable. It was a bit of a surprise when they began to exceed unit sales of desktop PCs. The first tablet PCs were rather clumsy too, but in the last couple of years ARM and improvements in touch-screen technology has made the grade.
In 2012, “It is estimated that as many as 20-30 million low-end tablets will be sold in the third quarter alone”
That puts the tablet as the new standard device for computing, at least for the mobile consumer of content, which is just about everyone. Between the smart phone and the tablet many people have everything covered and the old desktop and notebook technology is not really necessary.
see Digitimes – Tablet PCs expected to surpass notebook sales in 3Q12.
Hmmm… Where are those that continue to claim a tablet or other small cheap computer is not really a PC?
Expect unit sales of x86/amd64 PCs to remain flat or even decline soon. I would not bet on “8″ or “ultrabook” or any other campaign of Wintel to roll back the tide.
