I would only ever consider Noah Wyle for the part. You have to take in to consideration how close Jobs and Wyle got following the film, the peak of which the public saw when Noah impersonated Steve before (I believe) MacWorld.
If you really read up about Pirates Of Silicon Valley, you get an insight on just how personal Noah considered that role. He was relentless in getting every little detail, mannerism, and look just right. He perfected the role, and I would love to see him do it again on a more grand scale.
He's my only choice for the role, if he doesn't get it in this film, it would be a blind mistake on Sony's part, and a real disappointment which would make Pirates the better movie based on Noah's portrayal alone.
