It helps to think of how poorly "real" companies perform.  I mean, which software vendor ships bug free products?  It's a fantasy: and the difference is that startups (that care) can turn around fixes in the blink of an eye.  This leads into the greater area of support:  so many large corporations treat their customers like rubbish.  If you treat your customers with a baseline level of decency, they'll be happy.  The bar has been set so low that if you really care about support your customers will love you!<p>Honestly, the "professionalism" of large corps is nothing to aspire to.
