I was using my regular commuter train to get to work today. It is really striking to see that nearly everyone on the train is using a smartphone or tablet. I went back in time in my head. Well the last month and weeks were always similar. Crowded trains with tons of people using smartphones.It hasn't been like that forever. Only in the last 5 to 6 years -or so- the smartphone has started to invade my conservative commuter trains.Nowadays everywhere I look a bright and colorful screen smiles back at me (usually encased in one of the grey or black bars that represent our typical touch screen smartphone these days).If I have the time I make a mental note of the device and App I see. And I thought why not make a blog post out of these anonymous observations.Today was quite the usual train ride but still the plethora of Apps in use by my fellow passengers is intriguing. Todays mixed bag of Apps: Candy Crush SagaGoogle Play. App Store.The swap-3-style game is still so popular! Today I have seen a grown business man using a full size 9.8-inch iPad and tapping away on the colorful candy crush screen. Fascinating. WhatsappGoogle Play. App Store.It's still amazing how many people are constantly tapping away on their Whatsapp virtual keyboard. Today I witnessed several guys using Android devices and some rather up to date version of Whatsapp (material design). Words with FriendsGoogle Play. App Store.A bit of a unicorn today: I have actually not very often spotted someone who uses words with friends. But today a gentleman was eagerly picking the right phrases for his ongoing matches.
