Tim isn't a bad CEO, but I don't see why he deserves this nod. He's a logistics guy, which is great, but I've never seen him as some kind of influential visionary. Clearly neither does Wall Street, given AAPL's performance as of late. The iPhone SE and the new iPad Pro both should have been big deals, but the market reacted with a pretty solid "meh." Why? Because both were reactionary, not innovative products. The SE was a reaction to India and other burgeoning markets showing little to no interest in the full priced 6 or 6s versus cheaper but solid Android devices, as well a way to get rid of surplus 6 and 6s parts. The 9.7" iPad Pro was a reaction to the less than earth-shattering response to the full-sized Pro and the slowdown in sales for the iPad line as a whole. Don't get me wrong, both are solid products in their own right, heck I own the new Pro because I was due for an upgrade anyway and it's basically an Air 3 with a 100 dollar premium attached, but neither have exactly set the market afire with envy and copycats. If anything, the SE is copying those cheaper yet solid performing Android handsets like the OnePlusTwo and Nexus, and the entire Pro line is playing intellectual catch-up with the Surface Pro line.
If I had to guess, then, this nod has more to do with his openness regarding his sexual orientation than as a business mogul.
