Get a refurbished Dell or Acer laptop. Something that should only cost you around $200. Wipe the OS partition and install Linux or a preactivated bootleg of Windows 7. Install Libre Office, it's free and you can read and create pdf files. Libre Office has pretty much everything that Microsoft Office has but without needing registration or having to pay for it.

Oh, and don't ever bother telling ZOGbot management what you use today, they'll gripe and complain and squeal like pigs when you don't suck Microsoft's cock.
