If you think of it as a cash flow it helps. I remember the first Nvidia card I was given (as you needed to test your game on a variety of graphics cards).<p>This is back in the day of 3DFX, PowerGL, you know when there was actual competition in the market. The nVidia card blew them all away, they destroyed the competition. So how do you continue to grow revenue after you&#x27;ve destroyed the competition? Invitation, but not too much (what Apple does now, and very well).
