I imagine you're not a fan of the new MacBook Pros, so we'll stick with things you hopefully agree with.
In-house designed mobile chips with double the per-core performance of the nearest competitor. Exclusive business partnership with IBM. Next gen open source programming language and new file system. Ubiquitous services such as iCloud and iMessage. Over 100 new Apple Stores. Just really consider the larger picture and how much Apple have changed.
Where you see incremental updates because you lived through the curve, others see incredible growth and products that would not have been imagined in 2011. What you see as lack of vision because of a few belated hardware updates, others see a larger long-term vision because of the foundations Apple are laying.
And these are just things in the public eye. Apple have been known to be secretive from time to time.
So although you're entitled to disagree with these points, I don't think it's fair to say Tim has only ridden the coattails of Jobs' success. Regardless, I'm happy to end this debate here if you are.
