Consumers Will Need Variety of PC Interfaces

IDC recently revealed its new forecast for worldwide adoption of thirty one interfaces and technologies shipping in desktop and mobile PCs through 2010. Among key highlights of the forecast are the following:

- The user need for constant connectivity will steer demand for cellular wide area networking and broadband wireless options.

- The PC's role as the hub for consumer devices will drive adoption of high-speed interfaces, including USB 2.0, Gigabit Ethernet, and PCI Express.

- The arrival of Windows Vista will boost market demand for discrete graphics controllers.

- The emergence of DisplayPort will cloud the video interface landscape.

"The supplanting of older interfaces by the latest industry offerings is a game of timing, listening to customers, and observing market dynamics for a technology provider or OEM," said Richard Shim, senior research analyst for IDC's Personal Computing team.

"Remove an interface too early and customers will complain. Remove it too late and customers will bear needless cost and restricted design flexibility. Still the benefits of greater cost efficiencies and improving performance of systems will continue to be powerful motivations to drive OEMs' decisions."

"From a semiconductor perspective, chip providers should keep in mind that while a new technology may represent opportunity for sales of discrete ICs, the opportunity for silicon supplies to generate revenue from the technology may quickly pass due to pending integration into other silicon, such as the core logic chipset," added Shane Rau, program manager for PC semiconductors at IDC.

The only forecast item that I would question is the impact of Windows Vista. In fact, even Steve Ballmer is telling Wall Street analysts that their expectations for market adoption of the new OS are way too optimistic. Furthermore, the number one customer request voted to the top of the Dell IdeaStorm website is (as of today) a collective plea to pre-load Linux, instead of Windows.

The Cloud Imperative for Telecom Operators

The telecom sector is undertaking an update of its IT infrastructure. As demand for data continues to soar with the proliferation of 5G and new apps, network operators can't rely on their legacy hardware and network architectures. The process of "Cloudification" offers a path to reduce costs, improve efficiency and scalability, plus meet increasingly ambitious infrastructure sustainability goals. According to the latest market study by Juniper Research, cloudification spending by telecom operators will see tremendous growth in the coming years, rising from $26.6 billion in 2024 to $64.9 billion by 2028 -- that's a 144 percent increase in just four years. Telecom Cloud Apps Market Development "Telecom networks are becoming more complex; requiring increasingly automated network management systems. However, operators must insulate mission-critical traffic when reducing power, to guarantee quality of service for enterprises," said Alex Webb, research analyst at
