Never seen one here in Italy, and I think it's gonna take a little while... maybe after Xmas 2011
I think we Italians are more attracted to cell phones (everybody but me, it seems

)
But I tihnk there are two important factors for the spreading of e-readers to consider:
1) Availability of the devices at a decent price. Most electronic stores carry them now here too, but the cheapest I've seen is 199€... just 99€ more than the fair price for a market penetration, imho.
2) Availability of ebooks in Italian. No need to say more...
