1) Amtrak suddenly has much better Wi-Fi service on some routes -- starting with the Acela I am taking right now from DC to NY. Of course I admit that griping about the speed and reliability of a (free) Wi-Fi service, on a moving train, epitomizes having too few real problems to gripe about. But until recently the service really had been so slow and unreliable that I wished Amtrak would not even advertise it. That way, people who got any connection at all would feel lucky, rather than people expecting connections staring in frustration at their screens.
