Like the other guy said, IE7 isn't that rare in Portugal. it's a sensible baseline for SAPO, which, incidentally, runs the biggest web portal in PT (I work there).

And yes, corporate governance regarding browsers does weigh in heavily in mass-market sites here, so we have to make sure the layouts don't break - Ink enables delivering a predictable, working layout that degrades gracefully down to IE7 for that reason.
