When a tablet version of Chrome OS was teased back in February of last year, we found it a legitimately exciting proposition. Now that we have Android's Honeycomb iteration designed specifically for slates, however, we're having to wonder just why Google's still chasing that keyboard-less dream with its web-centric OS. CNET has been doing some snooping in and around the latest iterations of Chrome OS, where it's discovered numerous pieces of circumstantial evidence, such as a new onscreen keyboard, suggesting tablets are still very much on the menu. Chrome OS kicked off life on the development device known as Cr-48 and will resume availability this summer courtesy of Acer and Samsung, though we'd kind of assumed it would stick to notebooks now that Android's making a sincere effort on devices bigger than an EVO. Mountain View has responded to CNET's queries with a pretty inconclusive statement, saying only that "We are engaging in early open-source work for the tablet form factor, but we have nothing new to announce at this time." Check out last year's concept video after the break.
