"I made no argument comparing Amazon to Cognizant, or anything else." You are missing an important context of the discussion then. No matter what complex software working at large scale one comes up for an example, one can find problems with it. Every software has at least one problem that makes it a deal-breaker for at least one person. Even Linux, which is so popular in the tech world. These problems more often occur due to priorities than due to dearth of engineering competence. But these issues are orthogonal to the context of discussion. What you said about Prime's quality may be correct but irrelevant in the context of this discussion. "I think your claim that the likes of Cognizant cannot build things beyond IE-only AJAX-based chat apps hyperbole" Perhaps you can provide some examples then?
