I'm currently 40% of the way through Steve Jobs's biography by Walter Isaacson.
I didn't know too much about the man before reading this, but after seeing all the hoo-hah surrounding his death I decided to give it a shot. Steve Jobs as a person, comes off as a petulant, narcissistic, bullying, unstable, dogmatic man-child. He was extremely difficult to work with, which unsurprisingly led him to be forced out of Apple. (this description is only accurate up to the late 80s/early 90s, I haven't read far enough to make judgement of his character in more modern times)
I didn't know too much about how Apple started off and what his early achievements were. I was really surprised by how instrumental he was to modern computing as a whole, not just the Apple side of things. He may not have invented much but his main strength was his vision and desire for perfection. When he first came across an early mouse he immediately recognised its importance and he simplified its design, made it cheaper and incorporated it into the Graphical User Interface he was developing for the first Macintosh. The modern GUI used on most computers, to this day, is based on Steve and his team's ideas. Another thing I didn't know was his involvement with Pixar which he held 70% stake in. It was at first an extremly unsuccessful venture and was haemorrhaging money, yet he continued to pump money into it because it brought out his passion for art. Lucklily for Jobs, his persistence paid off and Pixar became successful with the release of Toy Story, 9 years after it was founded.
I've enjoyed reading about Jobs so far, he's an incredibly tragic, deep, and flawed character. I'd recommend this to anyone who is remotely interested in tech/gadgets.
