Apple

(AAPL) - Get Report

CEO Tim Cook is doing a great job since taking over from Steve Jobs a year ago today, according to a recent

poll

of

TheStreet's

readers.

Just under 75% of the respondents gave Cook a thumbs up, with only 2% describing the former Apple COO as a "disappointment." A little over 23% of

TheStreet's

readers, however, said they're undecided on the Apple chief, noting that "the jury's still out."

While Cook has cut a more reserved, less flamboyant figure than his fiery predecessor, he has earned

plaudits

for maintaining Apple's upward trajectory. The 51-year old has overseen successful launches for the iPhone 4S, the new iPad, as well a major Mac refresh, and is expected to debut the eagerly-anticipated iPhone 5 next month.

Crucially, Apple's shares have climbed more than 87% on Cook's watch, hitting a series of all-time highs, most recently on Tuesday when they traded at $674.88. The Cupertino, Calif.-based firm, which became the most valuable company in history in terms of market cap earlier this week, has a valuation of $624.94 billion.

Apple shares crept up 0.58% to $666.49 on Friday.
