I just got my Fit-PC2 Linux with Wifi and auto-on and I noticed something at the first boot of Linux:
It had the file "The.Dark.Knight.Prologue.2008.720p.Blu-ray.mkv" in the trash bin.
(it's a trailer/promo of the movie, not the full one)

Does this mean that anyone used my Fit-PC2 before I got it?
I wouldn't be comfortable using a system anyone had their hands on before me as I don't know what state it is in then.
I got it from the danish supplier listed on fit-pc2's website: http://www.linuxshoppen.dk

Or did anyone else notice it being there as some kind of demo for the Fit-PC2 to show that it can handle HD video? It ran fluently btw

This is one of the videos used by compulab for testing. The unit is not used.

Thanks for the answer
I found the other sample videos in the home/videos folder as well. Nice to put them there as examples of the power of the tiny beast
