Small, mobile and affordable PCs, often referred to as “netbooks” or “mini-notebooks,” were one of 2008’s hottest technology trends. Virtually unknown a year ago, these PCs pushed the design innovation envelope by enabling easy Web surfing, instant messaging, general-purpose computing (e.g., e-mail, social networking and photo sharing) and media playback in one small, ultra-portable device.
This convenience, coupled with an affordable price tag, makes these PCs a great option for many consumers!

How is Microsoft supporting small-notebook PCs with Windows 7?
“Microsoft is offering a clear path for Windows 7 across the board, so as we demonstrated at PDC, WinHEC and CES, Windows 7 provides a great user experience on small-notebook PCs.
With Windows 7, we’ve matched hardware improvements with some investments of our own. With Windows 7 we are on track to have a smaller OS footprint; an improved user interface that should allow for faster boot-up and shut-down times; improved power management for enhanced battery life; enhanced media capabilities; and increased reliability, stability and security.
These engineering investments allow small notebook PCs to run any version of Windows 7, and allow customers complete flexibility to purchase a system which meets their needs. For OEMs that build lower-cost small notebook PCs, Windows 7 Starter will now be available in developed markets. For the most enhanced, full-functioning Windows experience on small notebook PCs, however, consumers will want to go with Windows 7 Home Premium, which lets you get the most out of your digital media and easily connect with other PCs.” – Brad Brooks, corporate vice president for Windows Consumer Product Marketing.
