The Apple products & services that Apple does well are the ones that Steve Jobs uses (or cares about) and the ones he doesn’t use/care about are less good (or just plain bad). Jobs uses Keynote and it’s very good…but I’m pretty sure Jobs never has had to schedule his own appointments with iCal so that program is less good. Cloud apps and social apps are at the top of this list for a reason…I just don’t think Jobs cares about those things. I mean, he cares, but there’s not a lot of passion there…they aren’t a priority for him so he doesn’t really know how to think about them and attack those problems.
