Actually Not
Actually the biggest problem with OS/2 was that while Microsoft was working on it up front they were working on Windows in the background and waiting for their contract with IBM to expire so they could abandon OS/2. The first version MS wrote they wrote in 20286 assembler instead of C which made it extremely hard to move to the next generation of CPUs. MS did everything they could to kill OS/2 so they could have complete control and not be tied to IBM. Then when IBM took over they created the superior product but by then MS had the market and IBM didn???t market OS/2 very well and there were lots of folks that picked Windows because MS was the upstart taking down the evil empire.
