Your RV project is starting to sound like the building of Noah's Ark, bowser. Or a mobile crib to ride out the apocalypse. You know you only have three weeks to get it ready before the Mayan calendar runs out of pages, right? ;-) You didn't mention armament, at least, and that's reassuring. No MadMax anti-aircraft turret in the roof, right?

Not to quibble, but I want to make sure you understand that "having the same stuff on any computer he uses" doesn't mean that the stuff is actually on those varied computers. It means that all those computers have a Web browser that contacts the same central server, such as the one running Google Office. You might say that the chromebook concept is based on the lowest-common-denominator.

One school of thought is that this is a very good thing. It's the purest form of "cloud computing", in which your data stays in one place in the cloud while you roam around. I'm sure Google has a very good hardened data center, so your data is probably very safe. I'm not damning with feint praise here, those really are advantages.

My last word on tablets: They're one of those "any computer he uses" that participate in cloud storage; your stuff can show up on a tablet as well as a chromebook. You're not obliged to use all that local storage I touted. No matter how you slice it, a tablet is a superset of a chromebook because it can do everything a chromebook can plus it has local storage. And generally for about the same price.

But who am I to challenge the opinion of a 74 year-old PhD from Stanford?
