Rumors have been swirling for days now about possible delivery of Google's much discussed Chrome OS this week. GigaOm pinged a few people at Google to get confirmation on the rumor, and while they didn't get back a specific answer on whether the download will arrive this week, there was an invitation to a press event at Google's Mountain View campus on Thursday morning, billed by the company as "an update on our progress with Google Chrome OS." It sounds like everyone will get to try it very soon. Check out GigaOm for more details.
