Well let's be clear on one thing, what's the benefit of a desktop over mobile? Usually we say productivity. Editing photos, video, text, is all less productive, slower, less capable, more superficial on mobile. Adding an instagram filter is kind of iconic for mobile's productivity factor in my opinion. So is ChromeOS suddenly comparable to desktops if it can run mobile-productivity software? Of course not. Far from it. This may change as we're seeing mobile/laptop blur a bit (iPad Pro with force touch, a stylus and USB ports for externals, 12" Macbook with Intel Core M processor, for example. Or any of the 2-in-1s, the MS Surface etc). Once we see Mobile software running on Laptops, and see Tablets equipped with a keyboard/stylus, converging around the 11" form factor, with ever improving mobile chips, then we'll probably see more 'real' productivity software. But it's a bit too soon to call ChromeOS comparable all of a sudden. It's a great move, though. I remember you couldn't/can't even run Skype on ChromeOS. Soon, stuff like that will be of the past, without requiring massive Tizen-like investments to have developers completely rebuild a hundred thousand mid-high quality apps for your store.
