I tend to read the news in airplanes and hotel rooms alot (doesn't everyone?). The apps allow one to read off-line.

While I am almost always connected to Wi-Fi on the aircraft if it exists, the slow speeds I've observed recently can slow your browsing down tremendously.

Of course, a lot of aircraft still don't have Wi-Fi (hard to believe).

Hotel Internet speed is still the wild wild west. I was just in the Dearborn Inn for a few days and the speed was so slow that I couldn't even do a speed test.
