ON THE ACELA to NYC, and for the moment at least the wireless is working. I’m pretty sure that the economics don’t work, but you can’t fault Amtrak on the service. As I’ve noticed before, the folks who work on these trains take pride in what they do, and they do a good job. The Acela comparison makes flying seem even more like taking the bus than it already does. Plus there’s the absence of the intrusive yet ineffective airport security experience.
