What's Happening with Linux?

By now the open source Linux operating system was supposed to have taken over the desktop and left Windows in the dust. While Linux has made major moves in embedded systems and servers, it has a very long way to go before taking over the desktop.

It's impossible to find reliable numbers for the fraction of Linux desktop systems, because users can freely download Linux or copy it from friends. Windows apparently retains around 95 percent of the operating system market. Linux may have exceeded Apple's share of the remaining market and continues to grow, albeit much more slowly than the once predicted revolution.

Linux can be had for free, and it has little or no vulnerability to the virus attacks that plague Windows. So why isn't it taking over the desktop?

Probably the most fundamental reason is known as Linux migration. Weaning a PC away from Windows and converting to Linux may seem straightforward after the fact. But the process is not nearly as straightforward as some have claimed. You can see for yourself by checking out "So You Want to Use Linux?" at Linux Online!.

Another holdup is compatibility with Windows programs. Software can make the conversion in many cases, but legacy programs may be more difficult to use. As for the virus issue, there is concern that Linux will face the same problem as Windows as the user base increases. But that's a long way from now.

In the grand scheme of things, Linux and other open-source software are the wave of the future. Meanwhile, Mark Brunelli, News Editor of TechTarget has written a pair of articles that are must reading for desktop Linux enthusiasts. The first article is "Sizing up the Linux desktop market, Part 1." This article links to Part 2. Brunelli notes that the long anticipated Linux desktop revolution simply has not happened. Much more progress has been made in moving Linux onto servers.

While Windows still holds onto the great majority of desktops, Linux is gaining fast in the embedded systems competition. This includes Personal Digital Assistants (PDAs), the new generation of smart phones, robots, servers, gateways, audio/visual entertainment systems and a host of other systems with built-in processing power. Users may not know or care that their system is powered by embedded Windows or Linux. But the industry certainly does. A recent survey of embedded systems by LinuxDevices.com found that systems using Linux led Windows by 313 to 290.
