When it comes to the many responsibilities a CEO has I must say Tim Cook is doing a stand up job at managing operations, finances, CSR, expansions, outreach, and virtually everything else... except one major area. PRODUCT! Apple used to have a simplified product offering. And they bragged about it. In fact they made fun of their competitors for being overly complex and confusing. Now they are doing exactly they thing they made fun of. Trying to fill every niche in the market with something rather than simply making the best damn device for the best value.
I like Tim Cook, As a COO. or even CEO if someone else would come in and take a stronger position on the product line, because this thing is getting stale and bloated like a dead horse.
