Got an 1100 myself.
Had it three years now an no plans to change.
Had a go on the 1200 8v version and apart from a bit more rush after 5000rpm, couldn't really tell any difference.
I understand the later model is a bit thirsty too.
Maybe not an issue for many, but if you do a lot of miles it's something you have to consider with the price of fuel going ever upward.
I couldn't live with an old school air cooled twin that drinks more fuel than my 2.0 litre 170bhp car.
