Maggie put the piece of floor back and brushed the dust off the laptop bag before carrying it up the stairs to the kitchen. She spread an old newspaper on the kitchen table before placing the laptop bag on top and unzipping it. Maggie wasn’t quite sure what she expected from a seven-year-old laptop, but what she found was definitely not it.

It was a small, cheap-looking laptop. The dark blue plastic casing had an unfamiliar silver logo and a strip of tape with “C.S.” written on it. Maggie opened it and saw nothing out of the ordinary. It had a small keyboard and a touchpad, just as expected. The only odd thing was the row of three usb ports just above the keyboard. Maggie held her breath, feeling almost like a kid on an adventure, and pressed the power button.
