It is sales tax holiday weekend in my state, so that means I can get a new Mac and save a significant amount of dough. I currently have a 17 inch PowerBook G4, 1.33 Ghz. with 2 Gb of RAM. I use the machine to do all sorts of graphics and video work, using programs like Final Cut Studio, Adobe Creative Suite, iWork and iLife.

I'm interested in opinions on a new machine. There are some budget constraints, but I'd like to know the following:

1. Is the iMac 24 inch a viable option as a video editing station using Final Cut Pro Studio? One option I am considering is to buy an iMac 24 inch and a MacBook, doing my video work on the iMac and presentation work on the Macbook. What is your opinion about this?
2. I've looked on the Apple Store at both new and refurb MacBook Pros. If you had to pick a model, which gives the most bang for the buck? Do you think a refurb Core 2 Duo machine would be fine for my needs? Is there a disadvantage to buying a refurb vs. a new machine for the style of work I am doing?
3. Again, concerning Macbook Pros...do you prefer a 15 inch or 17 inch screen? Are there any disadvantages for going with the smaller screen? Both sizes come in both matte and glossy finishes: do you recommend one over the other for video editing?
4. Are Apple's RAM module prices in line with others? I would like to trick out the machine with as much RAM as possible right now. If Apple is high, who would you buy RAM from? I have used Other World Computing in the past, but I hear Apple is now competitive on this.

Thank you for any help you can provide on this situation!
