I think the Italian layout should have the same size Backspace key as the normal ISO and ANSI layouts.
I went to several Italian internet cafes - in Spoletto, Florence, and Rome - and I found 2 keyboards like this image (from Wikipedia):

The rest had the dwarf backspace.
Also, one was QZERTY, which screwed me up even more.
All were naturally terrible rubber domes.
Most internet cafe machines had admin permissions and a ****load of spyware. I ended up using a throwaway Google Voice account to keep in touch with my family in the US instead (and later I just picked up a Telecom Italia Mobile SIM, threw it into my AT&T phone, and used Rebtel to get cheap calling back in the US.) So I didn't really check my email or hop on Geekhack - I'm sure I was being keylogged...
