I'm a Mac/Final Cut Pro guy!

It does it all.

I shoot with SONY HDV cam,
* ingest with Final Cut Pro to internal drive,
* edit with FCP,
* create titles in LiveType,
* import graphics made in PhotoShop,
* add motion graphics made in Motion or PhotoPresenter
* add music created by others, or in GarageBand or SoundTrackPro
* export for streaming in a variety of possible formats
* and author DVDs with DVD Studio Pro.

I do have a SATA tower (not RAID'd), but I don't use it.

Right now I alternate my work between a Mac G5 PPC and an iMac20. I am convinced that I will be able to downsize my footprint by trading off the G5 for another iMac, yet gain productivity (altho the iMac harddrive bus is slower than the G5, eventough the iMac is Intel and the G5 is not).
