Conclusion: Halamka desperately wants Linux to work on a
laptop because he so admires the open-source philosophy of developers working together to improve computing. But he acknowledges that the OS—at least the RHEL or Fedora versions of it—is not ready for prime time. In fact, he was surprised that running Linux on the desktop was so problematic, even though he knew getting it all to operate properly the first time would be a challenge. "The fact that [Linux] can work most of the time [only] with tinkering—and after a team of PhDs figures out the exact configuration for a specific combination of hardware—does not scale for CIOs with heterogeneous laptop inventories," says Halamka. "I never got to the point where if I had to give a speech, I could open the lid of my laptop, launch my presentation and know it was going to work."

For Linux to become practical and affordable to run on PCs, he adds, hardware manufacturers will have to configure Linux software for specific machines. In part, this is because—according to a conversation he had with Red Hat executives—the company has no plans to support desktops and laptops.

Halamka notes that Lenovo is providing custom Linux configurations for its top-of-the-line T60 machines and that Linux configuration service providers such as EmperorLinux.com will custom configure SUSE Linux to run on Lenovo products for a fee of a few hundred dollars. He says that having one of these companies custom configure the operating system to a specific piece of hardware would prevent some of the problems he ran into and would dramatically reduce the amount of time IT staff spend configuring hardware and software.

As for the specific operating systems Halamka tried, he thought he'd prefer RHEL over Fedora for desktop use at CareGroup because in healthcare, reliability is crucial. Nevertheless, right now it's probably suitable only for limited applications, such as a public kiosk providing web access through Firefox or use of OpenOffice. As for laptop users, he concluded that even though Fedora was pretty unstable right now, support for new features is as important as reliability. He notes that Fedora is constantly improving because of those frequent updates. "In another year, it may be a full-featured, highly reliable, user-friendly system that supports laptops. In two years, the same may be true of RHEL," he says.

Meanwhile, he's not giving up on his quest for a simple, reliable Linux desktop operating system. Because his first attempts didn't meet his expectations, he plans to test-drive other Linux OSs, including Debian, Novell's SUSE and Ubuntu.
