Disagree, actually. The point I was making is that the CB is more capable than an xterm when online. Besides, when my cb is offline I can still make notes. This means drafting emails, tapping out ideas, and collecting my thoughts in useful ways. I did little else with my old windows laptop when it was offline.
The local storage features of html5 gives the device much more potential in this way, and Google aren't the only company racing to realise this potential in different ways.
