(1) How would you compare ease of animation?

(2) Render time?

(3) Is it possible to run both Poser 4 and 5 on the same computer? (the reason I ask is that I thought I remembered seeing something about this being a problem when P5 first came out.)

(4) How does P5 work with dual-monitors? (When I use P4, I have to re-set up the interface each time I use it)

(5) Where can I get the best price for P5 upg? (from a reliable reseller)

Thanks.
