Hard drives definitely don't work. Google confirmed that with me when I talked with them after the review. The promise this will come.

Extensions will work if they don't use some API thingee (that's the technical term) that Google doesn't find secure enough. Don't have my notes, but NP/API? Anyway, most of the stuff in the market they tell me should be fine -- but even there, not all of it will be, guaranteed, I was told. In short, Chrome in Chrome OS is not exactly the same as the Chrome browser.

On iTunes, we'll all be using music from the cloud. Seriously -- my second day interview with them will get into this. Maybe so. But if you're into Apple devices, you're still going to need iTunes.

On 3G, I have a 5GB plan that I've used for years. Never gone over my limit. But, I only use it for when I'm traveling, about 5 days or so per month. If this was your main plan, expensive. But Google positions it as something you can use if you're out and away from WiFi.
