From the New York Times:
Just because a bunch of individual ingredients are delicious doesn’t mean they’ll taste good when they’re all cooked up together. Ask anyone who’s ever sampled a 5-year-old chef’s rendition of chocolate chip spaghetti with meat sauce and grape jelly.
Similarly, many an electronics company has tried and failed to slap together a decent product from buzzword-compliant components – say, iPods, wireless networks, sound systems and personal computers.
