Pirates of Silicon Valley is quiet an old film now but I've got to see recently. It tells the early story of Apple and Microsoft as they create the PC industry. First thing to point out is that this film does not have the same level of production as The Social Network had and as a result at times may feel like a TV movie. However if you're a geek you'll find this entertaining given the portrayals of the key characters. I particularly enjoyed John Di Maggio's performance of Steve Ballmer.
