Doh! You're right. I use that all the time. I think the true winner is the command and option to the right of the spacebar.

Frankly, I never use the backtick.... and on my laptop I'm missing most of the other keys listed (no windows, context, flock, scroll lock, or anything).

Another contender might be the command and option buttons to the right of my spacebar.

But, other than those, I use damn near all of the yes on this thing.

Not too long ago I saw an interview with someone (sorry, too lazy to look up the name) who is trying to create a system of standardized swappable battery packs for cars. Just like toys and electronics, the solution for electric cars is not necessarily greater range and faster charging. Instead, batteries should be packed and installed in such a manner that they literally snap in and out. This would allow drivers to drive into any gas station that offered this service and swap out your dead or dying battery pack for a new, fully charged pack. This would function just like it does for propane tanks. You simply swap the tank/battery pack out and pay only the cost of the electricity. The station would "own" the battery packs and would charge them for their customers. Heck, in some places they could use wind or solar to provide the electricity for this and it would be very profitable (after start up costs). Also, this would remove the scary idea that maybe these battery packs have a limited lifespan and I as a consumer would have to pay for a new pack. In this scenario, the station would take care of that.

I don't think this is all that far fetched. And, if standardized, this could even be automated to the point where you just drive your car over a machine which removed the batteries from the bottom of your car and puts in a new one. You swipe your credit card and you're back on the road.

Food for thought. :)
