If Windows is a dead end, what's next?

Windows 7 looks like lipstick on the Vista pig. Maybe it's time to contemplate the PC after Windows

Legacy client apps could run in virtual machines that appear to the user to be part of the "OS," just as Mac users with VMware Fusion and Parallels Desktop can run Windows and Linux apps as if they were Mac OS X-native today. (VMware Workstation and Parallels Workstation likewise let Windows and Linux users run multiple OSes on their systems.) Using VMs to support today's fat client approach would allow the "OS" to evolve without breaking the legacy apps, and let everyone move more quickly away from the fat client world we live in today -- one where, in Microsoft's case at least, OSes get much fatter each rev.

In this world, Adobe and Microsoft may be the new OS providers, supplemented by virtualization engines from Citrix's Xen unit, EMC's VMware unit, or Microsoft. Today's browsers may not be necessary, except as perhaps containers for bookmarks and other file management activities.

The wild card is Apple, which appears to have no strategy for the cloud other than offering application stores for downloading to its desktop and mobile client OSes. But there are hints in its vague goals for Mac OS X Snow Leopard, due in summer 2009, that Apple is considering a scalable OS that could operate in a streamed or mixed client/Web environment. Apple says it will make the next Mac OS X consume fewer resources, and its iPhone OS is already a subset of its Mac OS. But Apple has done nothing public involving virtualization, streaming, or RIA technologies -- the apparent foundations for the new PC order.

Whether Apple is part of the new desktop order, PCs would be essentially network-optimized thin clients that have enough memory and storage to run local apps in VMs or cached streams when disconnected from the Internet, but they wouldn't need a traditional OS to function.


Everyoneloves to predict the future. InfoWorld devised five possible scenarios for Microsoft after Bill Gates' retirement. Which do you believe in?

Think this is science fiction? A company called DeviceVM has an instant-on technology for Windows PCs that boots Linux first to run enable browsers to launch immediately. Windows follows along in its own sweet time. Dell, Hewlett-Packard, and Lenovo are working on similar approaches -- marking a significant decoupling from the traditional client OS mentality. Microsoft says it is investigating a similar concept, using a subset of Windows to run browsers and so on before the whole OS loads. As more apps are browser-delivered, people may find they can get by without the full OS. By the same token, PC makers could make loading the whole OS an option at startup.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
