Well I don't know about Apple "responding" (Score 1)

This was a no brainer for Apple to release iMovie for free for everyone because it was easy to do, and it helps build up the consumer market with people who don't necessarily have i-macs. Although it's a nice product..it's still no Adobe Premiere or After Effects. Just like the free program Gimp can do a lot of things Photoshop can do... it's still not as robost as Photoshop or replaces it. As far as Apple's reponsiveness, I would say ask Mac game developers how responsive Apple has been in the past. They've been banging their heads into the wall trying to get Apple to help make the game market and development stronger on the Mac side...personally I haven't seen much change..
