Google unveiled more details about their Chrome OS this week. Google also released the source code as open source, so if you have time and skills you can actually run Chrome OS now.
Tweaktown did just that and published this hands-on review.

Quote from the review: "If you followed our live blogging from yesterday you know that Google made some really big claims. They claimed a 10 second boot up time and they claimed a quick and easy to use OS. They even showed us that with their demo unit they had working. The problem is that unless the source code we have is not what they were using at the demo Chrome OS is bulky, awkward and about as un-user-friendly as you can get. The snappy OS and fun items were just not there in the version we played with. Finding options and features is not easy; you really have to hunt around for what you are looking for to find it.

To us it felt more like a badly coded browser than an OS we would want to use for an extended period of time. In fact, as I was writing this Chrome OS, rebooted inside VMWare several times and gave the error that it had not been shut down correctly. Speaking of shutting down, after two hours of hunting and searching, we were not able to find any way to properly shut the OS down. The option simply was not there."
