I test drove the 1.0 (albeit with the manual as the 6f auto wasn't available for that engine stateside yet) and I was impressed with it. We wound up going with the 2.0/5 speed manual because it's what my wife had her heart set on despite my not really liking the gearing of that transmission. Like Anthony said, it's not a barn burner but it's definitely going to surprise you for being such a small engine.
There's a tread with my immediate impressions somewhere in the Focus section on this board about it.
