A Steve Jobs to-do list made at an off-site brainstorming session listing a set of technical challenges remaining for his team to solve. While building the NeXT computer, Steve wanted to meet the challenge that Nobel laureate Paul Berg had set to build an affordable workstation for education that had more than one megabyte of memory, a megapixel display, and a megaflop of computing speed to allow a million floating-point operations per second. Today we measure in gigabytes and gigaflops, but at the time, combining these attributes presented considerable technical hurdles.
