"For example, the presenters said Chrome OS netbooks wouldn't be allowed to use hard drives (Flash memory boots faster) and that Google would specify which Wi-Fi cards it would support."
The aim, says Pichai, is to make your PC work like a TV: you just turn it on and in a few seconds you can do what you want. In this case, it's assumed that what you want to do is check your email, use social networking sites such as Facebook and Twitter, look up maps, and so on. However, Chrome OS takes the idea even further than Android or Apple's iPhone by eliminating local applications. There won't be a Chrome OS app store, and Chrome OS netbooks won't run Android apps, because all the apps are online apps. Eliminating local apps means Google can strip out everything that isn't required to run the Chrome browser, so the final code should be smaller and faster. It also means Google can prevent users (and malware writers) from messing around with the operating system: if a single byte is changed, it can replace the whole thing.
Sounds like a complete waste. (edit) And if you look at the comments, then you can see quite a few agree with me,
I like the idea of having your OS stored online - but the rest of it is silly! If your OS is being stored online, why no hardrive? With it not it physically on your hardrive, you have no worries of being infected permanently, and if they can implement fast, online OS, then I don't see how they couldn't quarantine each file to its small area on a HD like Sandboxie.
P.S. Irony: I'm listening to a song called Chrome.
