I guess my point is that people don't always have wifi. I want to use my laptop on the plane (though some airlines now offer super-exorbitantly-priced wifi, I still refuse to pay for it) or in the back seat of a car.
I should be able to tap away at a document or use a Thunderbird-style "send emails when you next have connectivity" mail client.
My understanding is that the Google apps don't currently offer this.
Try it out on your Windows laptop, if you want, and you'll see how it works. My understanding is that this functionality is there to some extent, but I haven't used a laptop without wifi in long enough that I have no real idea.
As far as I know, most Google branded apps can do this and there is nothing preventing third parties from doing it too. You can probably boot your laptop with a ChromiumOS live stick and check it out.
