Cody, keep in mind that a wall wart is a cheap device. The USB ports on a laptop, desktop or cable box are kind of expensive to fix. There have been horror stories. Just sayin....
My computer is 7 years old. Laptop is 5 or 6. I try not to use my laptop ports, but I don't mind living dangerously when I'm already itching to rebuild both. Otherwise, I definitely agree.
