Imponderables

David Pogue has a long list of good questions. Here’s just three of them:

• Why is Wi-Fi free at cheap hotels, but $14 a night at expensive ones?

• What’s the real reason you have to turn off your laptop for takeoff?

• Why don’t all hotels have check-in kiosks like airlines do?

The answer to the second of these I believe is so laptops won’t go flying around if the plane stops abruptly in an aborted takeoff and to keep passengers from being distracted and encumbered during an emergency evacuation.
