According to industry analysts, personal computer sales are down across the industry as consumers turn toward newer devices such as smartphones and tablets and await the arrival of system upgrades like Windows 8.

PC sales for the second quarter in the U.S. were down between 6% and 11% compared to the same period last year. The drop marks the seventh consecutive quarter that laptop and desktop sales have fallen.

It remains to be seen whether Microsoft's new Windows 8 operating system will be a big hit with consumers. The OS was designed with mobile products in mind, but if consumers continue to choose iPad and Android tablets over new hardware that runs Windows 8, some traditional PC companies could see sales dip further.  Already PC manufacturers are scaling back inventories.

Analysts say Ultrabook devices are still in the early adopter phase. These devices are designed to offer the thin, mobile convenience of a tablet while featuring the productivity power of a laptop. So far, though, they have not contributed significantly to overall PC sales.  Interesting times ahead for the industry.
