Re: Color 1.5.1 first impression

I'm about to upgrade to Final Cut Studio 3 from 2. I had nothing but frustration trying to get Color to work on my MacBook Pro, it would crash and lose all of my work as soon as I tried to render. After a lot of time on the phone someone from Pro Apps told me it wasn't designed to work on MBP's and that my system couldn't handle it. This was when my computer was brand new, 2.4GHz dual core, 4gb of Ram and 7200 hardrive.
I gave up when a friend at a major post house told me they were having Color problems and went back to their old workflow.
My question is, have there been any improvements with Color? Any tips to getting the most out of the FCS 3 version? I'll be grading XDCAM 1080P footage.
Thanks
