For many different reasons too ! Some were a bit petty/misguided :
- Microsoft was mostly contractual on the Xbox, Nvidia didn't want to lower the price of the chips over the lifespan of the 1st Xbox which was a huge no-no. And some technical people also had a terrible experience (some people in the DirectX team had strong thoughts about working with Nvidia).
- Sony was mostly about terrible tech support and not wanting to share enough technical details which hampered AAA devs a whole lot, to the point most ended up using the SPUs in very creative (and technically fascinating) ways to compensate (the GTA V engine on PS3 was truly impressive in that regard).
- There were some minor (but acrimonious) back and forth with Apple over a failing gen of GPUs (G80s if memory serves), but the large fallout came for the same reason as for the rest of the mobile industry : the Kepler licensing initiative.
Long story short, Nvidia tried to assert patents on mobile GPU (ala Microsoft on Android, as a way to "sell" their exit of the mobile market to investors). They then sued Samsung and Qualcomm [1]. Samsung countersued Nvidia, which had to settle as Samsung was close to winning a ban on imports from some Nvidia products [2]. Many of the patents Nvidia tried to assert were thrown out and they had a terrible legal time.
The damage that ill thought strategy did to Nvidia is hard to measure but there's not a single mobile company that wanted that acquisition to go forward and many are probably quite relieved after this.
