Can you tell us where in Europe you did see it?
Cause I went to a big electronic store in Germany, Hamburg. I looked at the MBA Rev.B and first I thought the lines were gone. But then I opened Google.com and I did see them. Although they were much less noticeable than before, but this might be due to the bright light in the store.
I couldn't check the screen model, as the options were 'locked' by the admin.
So far - unfortunetly - I did not see any MBA Rev.B without the lines. If anyone knows where in the north of germany I could see one I would be glad if you let me know! Cheers!
actually it was Saturn/Mönckebergstr. They had two units on display last week: one 1.8 ssd and one 1.6 hdd. I compared them side by side. Your welcome to do that as well and report back. I am very curious if you still can see them... If so I check back as well.
