Steve Jobs, the co-founder of apple has resigned as CEO of Apple Inc.  following years of health problems.

In his resignation letter he said If there ever came a day when I could no longer meet my duties and expectations as Apple's CEO, I would be the first to let you know. Unfortunately, that day has come.

Job's successor Tim Cook has firmly stated that Apple isn't going to change, but the news has still stirred a mass reaction on Twitter.
