My mom has owned a PC laptop for two years before she broke it this spring. Since I was going to be traveling for the summer, I let her use my Macbook while I was away. About two weeks into my trip, my mother called me and said “Wow, I love your computer! Did you know you can unplug it from the wall and use it at the kitchen table or on the couch- I even took it out on the porch yesterday!?” It took me another week to convince her this wasn’t a feature exclusive to Apple computers.
