Eager to play with Google's just-released Chrome OS but don't want to waste your time if your hardware isn't supported? This simple chart from Google helps you figure out whether or not your equipment can work with current Chrome OS builds.
Populated by developers who've played with Chrome OS and gotten it up and running on their systems, the chart specifies how (and if) features like Wi-Fi, trackpads, and suspend/resume work on each system. You can also read about any caveats or other comments from the developers who've played canary-in-the-coalmine. Currently most of the hardware in the list is of the netbook variety, but it's a good place to get started if you're an early adopter but you don't want to waste your time if your hardware's not going to play nice.
Remember that Chrome OS is still extremely young and still rough around the edges, so unless, as Google puts it, you "aren't afraid to take a screwdriver to [your]computer", you'll probably want to wait for Chrome OS to mature a little.
