Thank goodness for your smartphone: You buy shampoo while you're waiting in line at the post office, shop for birthday gifts on the train ride home and stock up on socks to pass time at the airport. It seems like you're getting so much done, but shopping on your phone (or tablet—basically anything with a touch screen) could lead to spending more than you would if you were using a laptop or desktop computer. It's not simply that you switch to autopilot: New research from Boston College shows that consumers feel a deeper affinity for products they touch on a screen. The study's authors theorize
that this is because technology has made it easier for them to feel as if their iPads are an extension of themselves.
