Anand's Thoughts on Google's Chrome OS

Microsoft’s Inaction

Fail to adapt and you’ll usually leave a lane open for a competitor to come in and innovate. Although Microsoft dominates the netbook market, I don’t know a single person who would call using a netbook running Windows 7 a pleasant experience. There’s a ton of disk swapping, applications can take forever to launch and although you can do a lot with a netbook, you typically don’t want to. Microsoft needed to provide a lightweight OS optimized for the netbook experience a couple of years ago. It didn’t. So Google is.

The selling point behind a netbook is that it’s small, cheap and fast enough for browsing the web. The problem is a netbook isn’t fast enough for running the OS that you need to run in order to get access to the web.

Microsoft refused to revamp the OS, so Google decided to put forth an OS based around a web browser.

It’s called the Chrome OS and it’s built off of Intel’s Moblin distribution of Linux. and it's built off of Google's own Linux distribution (ed: sorry for the mixup, Google tells us our earlier Moblin information was incorrect). There’s no conventional desktop, you turn on your Chrome notebook and meet a login window followed by an instance of the Chrome web browser.

Google first announced it almost a year ago, but yesterday it fleshed out additional details about the Chrome OS and the first platform to use it.

Learning from Our Mistakes

There are two things that plague the PC user experience: security and ease of use. If you’re a software vendor, there's a third one too - piracy. When building this new category of lightweight OSes and platforms, most vendors want to be the next Microsoft while avoiding making the same mistakes.

It turns out that you can solve a lot of these problems the same way: by closing off the platform.

Chrome OS is a lot like a modern smartphone OS. The only way you can get applications onto the device is through Google’s Chrome web store, and the only way to get applications into the web store store is to have them approved by Google. Right away that means viruses, malware and things that would hamper the user experience are out. The same approach is taken by Google with Android as well as Apple with iOS.

Google further improves security by sandboxing virtually all aspects of the Chrome user experience. Individual apps don’t have access to one another and everything running on a Chrome OS system is version checked against basic code stored in read only memory to make sure unapproved code isn’t running. If it is, the OS can warn the user and automatically restore itself to a known-good state.

All user files are encrypted on disk and decrypted upon use using your login username and password as a key. As long as no one has access to your password, they can’t access anything you’ve stored on the system.

All OS and app updates are handled automatically by Chrome OS. Updates are installed as they’re available similar to how the Chrome browser works on your PC or Mac today. By default you never have to interact with an update dialog box, updates just happen automatically. Unfortunately as we’ve seen with the Chrome browser, this can result in unexpected instability if Google pushes out an update that wasn’t well tested. But from a security standpoint, having a constantly updated OS and apps ensures that security will never be compromised by a user failing to install the latest updates or patches - a definite problem that faces PC users today and one Google hopes to avoid on systems running Chrome OS.

Although this all sounds very Apple like, Google is committed to offering a free-for-all mode at least on its Chrome development platform. The first Chrome notebook that Google is providing as a part of its pilot program features a physical switch underneath the battery that allows developers or enterprising users to turn off all restrictions and run any code you want on the system. Presumably this includes installing your own OS on the hardware or whatever software you’d like. Assuming this feature makes it to retail Chrome notebooks, you shouldn’t have to worry about jailbreaking your system.
