Bleh, that cluttered circular display would irritate me even without the bugs Gitlin mentions.
I actually liked the toggle switches on the older models- they were sort of charming and quirky, which was the point of Mini for me (besides the handling). They had a learning curve to be sure, but I suspect the "too slow to load" infotainment system would similarly take time to get used to. Especially if I'm trying to use it while driving, which just sounds like a recipe for "incidents".
