I pulled out my laptop and powered it on. It was a bulky, heavy beast, almost ten years old. I’d found it in a trash bin behind the abandoned strip mall across the highway. I’d been able to coax it back to life by replacing its system memory and reloading the stone-age operating system. The processor was slower than a sloth by current standards, but it was fine for my needs. The laptop served as my portable research library, video arcade, and home theater system. Its hard drive was filled with old books, movies, TV show episodes, song files, and nearly every videogame made in the twentieth century.
