Here's the most important thing: The Internet itself can't be trusted to handle 100% of our computing needs.
Google's own Blogger service went down for more than 24 hours this week. To restore service, Google rolled back to an older, backed-up version, which didn't include 30 hours of blog posts for Google's millions of users. As I was writing this column, Google was working to restore the lost posts.
Such disruptions happen all the time, even for cloud-based services that are supposed to be bulletproof. Amazon's EC2 website hosting service -- which exists to provide fail-safe, totally reliable hosting -- experiences catastrophic outages. The most recent outage occurred in April. The glitch took down Foursquare, Reddit, Quora and other major services. It took Amazon four days -- four days! -- to return service to normal.
Cloud computing is great, but only in combination with "regular" computing. The only reliable way to manage data is to store and back up locally, and also to the cloud.
The Chromebook model requires the user to have a fully functional machine, browser, connection and Web services. Without each and every one of these elements working perfectly, a Chromebook is nothing but a tray for serving snacks.
The big question is this: Do you trust Google to keep this program going?
Google has gained a reputation lately of simply canceling projects that aren't working out. The company has killed off Wave, Lively, Answers, Dodgeball, Video and other high-visibility projects. People start getting excited about a platform, then one day Google makes an announcement, pulls the plug and that's it.
Even more relevant is the cancellation of Google's Nexus One phone. Google came up with a new way to sell phones and rolled it out in January, 2010. The Nexus One was available only online, and unlocked. Google assumed that users would be happy to provide tech support to each other, and so the company didn't set up any way to support users. They assumed wrong. The phone was taken off the market in July.
The question on the minds of businesses considering the Chromebook is this: Will Google end support?
Businesses are used to buying equipment from companies like Hewlett-Packard, IBM and others that tend to support their products even if they're not runaway successes. And they provide migration plans if they do end product lines.
If a company is going to buy 300 Chromebooks and reorganize its IT department accordingly, it's going to need assurances that the platform will be supported for at least a decade. I haven't heard Google give that assurance.
