Yes. I had the old Mac Pro silver tower, but skipped the trash can Mac Pro in favor of a maxed out iMac and then an iMac Pro which I’m currently using. Lack of PCI slot aren’t a big deal when you have the Sonnet Echo Express that works great.
I do think the new Mac Pro will be a winner for audio people but it’s going to be $$$$. So we’ll see how many people actually buy it.
