Not even Dell UK
I actually tried the link you provided and couldn't find any Linux computers.
The link "Shop for Ubuntu laptops" shows Microsoft operating systems ONLY!!
Perhaps there are indeed Linux systems on Dell UK, but it almost seems like Dell is ashamed of Linux or something.
It's not really relevant since the topic was a lawsuit in Italy, but I think it's a clear sign of a Microsoft monopoly.
Besides, it's not like the UK is representative for the situation in the "real" Europe. These crazy islanders don't even use the Euro to pay for things! Go figure!
