I love my 800 - although the faults do bug me. I've done 10k commuting miles now, and at service time I get a 1200 as a loaner. I never want to give it back, when I get back on mine I think "wheres the bike gone" - the 1200 has a much more substantial cockpit.
I find the 800 very top heavy, and very tall - not great for traffic. Nowhere near as nimble as my old TA. If I had the funds and could justify the extra fuel for commuting, I would have a 1200. Hopefully the larger front sprocket I fitted today will improve the m/way ride.
jmho.
