The Developer channel on windows, mac and linux has been updated to version 17. We should see soon in Chrome os developer channel updating to chrome os 17 and 16 moving to beta, and 15 moving to stable channel. I don't know when it will be but I hope it is soon. I like Chrome os 15 but it isn't on stable channel channel yet. I hope it comes soon. Stay tuned, once Chrome os 15 hits stable I will post about it. see you for now!
