Cannot use personal laptop (Score 1)

My company doesn't allow me to use personal laptops, so I havent bought one yet. They insist that I use the company issued laptop at home and they have a right to demand it back any time (they havent done so in years, but still they have the right). I do have my personal data/photos/articles on this laptop but I trust my company to give me at least 1 day notice so that I can backup my stuff before returning the laptop.
