Yes, I agree, CS4 crashes MUCH MORE than CS3 ever did. My system was built by an expert, and I have a lot of money in it … 4TB, plus 1TB for backup… plus an external Seagate 2TB backup drive.
I have a feeling that CS5 will be a big improvement, so I would not personally consider FCP just yet … it has its problems too.
Even with the occasional crash, I am beginning to like Premiere and all of the rest of the CS4 package. I am a former “Edit” user, and it took me a while to get cozy with Premiere.
I have seen NLE’s come and go over the past several years, but Adobe and Apple both have deep pockets … they’re not going anywhere.
