What is the Future of Desktop Computers Since the Development of ARMS ?

Some experts are predicting that the desktop computer as we know it could be in danger.
Over the past several years the demand for desktop computers in the home has been steadily declining, displaced by notebooks and all-in-one systems. In fact, 69 percent of PCs sold in the last quarter were notebooks, compared to the falling 22 percent that were desktops. This has been the trend ever since notebook sales caught up to desktop sales back in 2008.

Also, another cause for worry is the recent explosion of ultra-moble products, specially smartphones and tablets.  In just a few years, smartphones and tablets have made huge strides in performance.  Older pokey computing devices have become pocket-size powerhouses capable of many of the same basic functions as an ordinary desktop.  The major reason for this is the development of ARM, a versatile processor microarchitecture that emphasizes power efficiency, yet is high in performance.

Analyst Robert Enderle of the Enderle Group says, "if current trends hold, there should be at least one credible ARM player in the desktop space in five years." The way I view it, considering how unpredictable new developments in emerging technologies have become, I"ll take a wait and see position.
