Legendary Apple CEO Steve jobs resigned on Wednesday, citing health concerns and his inability to meet his duties and expectations as Apple's CEO.
His retirement was not a complete surprise given his three medical leaves, nearly decade-long battle with pancreatic cancer, and liver transplant in 2009.
But in resigning, he marked the end of an era at Apple - the company he co-founded in 1976 - during which he took it from its dismay loss in the computer market to becoming one the largest companies in the world.
In the process, Jobs transformed the space for consumer electronics.
There were portable music players before Apple, but the iPod transformed the market and created more demand for it. The iPhone shook the cell phone industry. The iPad effectively created the tablet market.
Upon his retirement, effusive praises and accolades have poured in for the Apple CEO. Below are some of them.
