Right, but I already have a 003 I'm wondering if it's easier to arrange and use (such that it is worth $300)
Are you using a laptop? If so PT10 would let you use the built in audio so you could mix anywhere without the 003 having to be connected. You could mix on the bus, in the back yard, in bed or in the back row at church.
PT10 does require a newer Mac. You might do fine with PT8 for quite a while before the advantages of PT10 reach a tipping point.
Yes, I am using my Macbook Pro (Intel Core 2 Duo, 2.53 GHz, 4 GB RAM). It's not an i5 or i7 but it's still very fast.
Regarding plugins - do you think it's worth the upgrade? I mean, will I get that many more tools (compressors, EQ, etc, effects) that are usable? (Sorry for the number of questions, just want to make sure that it's worth it)
