yea man, I dont think Greg is off his rocker at all, I use multiple DAWS to get the job done but Reason easily does 99% of the work.There are a few great programs to get Reason syncing to video
http://www.reasonsync.com/ReasonSync.html and
http://www.retouchcontrol.com/site_page.aspx?pageid=46 being a few of them. I actually agree with everything he says. Reason has hands down the best workflow of any DAW on the market, but plugins sure are nice, as is things like native video sync. I LOVE Logic, however I worry about being in bed with Apple on the pro app side, so my other DAW of choice personally is Ableton. Reason just works far to well for my needs but I certainly understand where he is coming from. If I lived and died my film composing I probably would be looking hard at Logic as well.
