Shirley is retired and is looking for a computer. Leo says that a Chromebook is probably the best option for Shirley, and she'll need an internet connection. Shirley could also get a Chromebook with LTE.
Another option is a tablet like an iPad or Samsung Galaxy Tab. She shouldn't get a cheap one, though. Leo advises getting one with LTE so that she doesn't have to rely on Wi-Fi. T-Mobile is a good option. Leo also advises a deal of $25 with unlimited data from them when she buys the tablet up front. That's a good deal.
