A no-OS-computer? You must be a pirate!
After reading this piece about a Linux keyboard PC , I got excited. I checked the vendor's page and, sure enough, there was a "NO OS" option. A day later, I received it and, with it, there came a surprise. They had included Windows 7 Professional 32 bits and were charging me for it!
I immediately contacted the sales representative to ask why they were forcing Windows on me if I had explicitly selected a "No-OS system"(I changed the names).
So, she said that she had done it because, that, way, I could deduct from the price the cost of Windows (?!) as long as I had "OS licensing". This showed to me that, thanks to Microsoft's dirty campaigns, you are seen as a pirate when you request a computer without any OS.
