In a company that has hundreds of products, is that really so hard to believe? Mega successes... mega failures. Still massively successful?
Look at Apple. They were at the top with the iPod. Then the iPhone. Then the iPad. Massively successful. Yet they still release turd products like one button mouse, Apple TV and the G4 Cube.
Or Microsoft with their massively successful products and massively unsuccessful turds.
It's not like other companies don't have horrible customer support... Nope... just Google. /rolls eyes
