A couple of weeks after describing Google as more innovative than Apple, and suggesting that Tim Cook was vulnerable to a shareholder revolt if he didn’t quickly release disruptive new products, Steve Jobs’ biographer Walter Isaacson has downplayed his remarks in a round-table discussion on Bloomberg TV.

I think [Google is] very innovative. I was not trying to contrast it to Apple or something. I know, all the Apple fans got mad […]

The one thing I will say is innovation is great, but it ain’t everything. It’s not the holy grail. Execution is what really matters, and Apple is the best at execution … 

Isaacson also dismissed as irrelevant suggestions that poor sales of the iPhone 5c suggested Apple didn’t know how to make low-end products.

I don’t think Apple will ever be great at doing low-end. It really makes insanely great products, to use a phrase Steve used 30 years ago when he launched the Mac.
