Yes and no. Yes, it is really MS Word, and it isn't a mock-up, and yes, it looks and feels like it is running on the tablet, but no, it isn't running on the tablet, it is running on my Linux computer (at home), using Wine. I'm using SSH X-forwarding to use Word on my tablet; this means I can only use it when I have an Internet connection. I was surprised at how well it runs over WiFi, I was expecting to be painfully slow. It is actually useable, for things like converting Word docs to PDFs, etc. I have to use my Bluetooth keyboard.

Hmm, I wonder if PowerPoint works as well as Word?
