The writing is on the wall. Despite a major push to sell the much-maligned Windows Vista, customers aren't buying. Nearly two years after Vista's release, Windows XP remains the standard desktop OS in business, and Microsoft has extended its availability three times (currently to August 2009) due to customer demand. Microsoft itself forecasts just 2 percent growth in Vista sales in early 2009, after lackluster sales in 2008. And that's after forcing customers to buy Vista to get XP "downgrades."
But early reaction is that Windows 7 is just a cleaned-up Vista. It's essentially the same kernel and the same OS, with a couple new technologies thrown in, such as the Surface-based multitouch capabilities and the ability for developers to ribbon-bar-enable their own apps for better consistency with Microsoft's new UI approach (one that people either seem to love or hate). "It's not anything radical," says Neil MacDonald, a Gartner analyst who follows Microsoft. "It's a polished version of Vista."
If Windows 7 is more of the same, then maybe it's time to conclude that Windows is a technology dead end. Last spring, Gartner warned that Microsoft had to radically change Windows or watch it fade into irrelevancy. Windows 7 is not that radical change.
A Glimpse at the Future of the PC
So what comes after Windows? Already, there are signs of what that might be. Cloud-based delivery of services makes the browser, not the OS, the "kernel" of tomorrow's PC. Rich Internet application (RIA) technology gives those services the richness that the first generation of the Web could not even contemplate, despite early attempts with Sun's Java and Microsoft's ActiveX. Virtualization lets you mix OSes together, as VMware Fusion and Parallels Desktop have proven admirably on Mac OS X. The emergence of desktop virtualization and application streaming allows for even richer apps to be delivered without the weight of a fat OS on the client side.
Put these together, and you can see the future of the PC, says MacDonald. The client OS -- Windows, Mac OS X, Linux -- becomes irrelevant over time. Instead, the browser evolves into a thin client that lets PCs run services that stream from the datacenter or run in the cloud. The new breed of apps would be services that run through technologies such as Adobe's Flash and AIR or Microsoft's Silverlight -- it's no accident that both sets of technologies run on any browser and on the main three OSes of today (Windows, Mac OS, and Linux).
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.

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.
Of course, such a transition involves many pesky questions, notes Doug Dineley, Test Center executive editor at InfoWorld. For example, where do drivers live? Is there a universal set of drivers that all hardware makers write to? If the new PC is essentially an amalgamation of services, streamed apps, and virtual environments, there are still devices and peripherals to be managed. The hardware doesn't go away.
