Michael - I've played with all of these. In the context of "different strokes for different folks" I'd say you are correct - use the tool that works for you. In terms of what is a professional product - I disagree - Protools far exceeds these programs. One reason is the key to Protools -- the TDM hardware. Logic is the only program you mention that can use Digidesign hardware - but if you're going to buy the TDM hardware, you might as well use the Protools software like the rest of the industry. Who knows where Logic will go now that Apple has purchased it - maybe it will compete with Protools on a higher level but more likely it will be blended in with their consumer marketing. In sum,
I consider Logic, Cubase, Nuendo, Sonar and others to be very much pro-sumer products geared mostly at hobbiests - not that there is anything wrong with that. But if you want to truly use what the pros use - Protools is it.

Also, Windows Operating System (all flavors) is great for lots of things - audio is not one of them. I can list lots of reasons why but I'll give you one to chew on... viruses. Mac OS 9 has none. Mac OS X I think they just discovered one. Mac OS X has great potential for audio applications but much is still in transition. The first iterations of OS X really were poor. So far so good with Panther however.

Raj -

No offense but your pictures reflect a lot of clutter. They are also squeezed and distorted. I'm sure your intentions are good. But as we've discussed before - you're missing a whole world of great recording capability using Protools 002 - you've got enough Mics and Pres - bite the bullet and grab a G5 with Protools HD Accel 2. You'll be in heaven, I guarantee it.
