On a side note. Requiring 8 GB RAM (as Tim Kolb says) for editing app is ridiculous, and cannot be usead as an excuse for lazy code. Heck, I have edited a 20 minute episode of a biking show (admiteddly SD) on my 4 years old laptop with 1 GB RAM and Vista (!) with Avid MC3! I had another episode (same material, another edit) edited on a Premiere CS3 machine with 4 gigs of RAM, it was opening the project for 4 minutes (avid just popped open). Something similar can be said about FCP, which is not as efficient as Avid, but is really quicker than Premiere.
Nice thing about Premiere is a wide support of formats, but, as you may know, if something is featured on a product box doesn`t necessarilly mean it really works – an example would be the painful AVCHD support, unability of scene-splitting HDV (come on, 80 USD Pinnacle has that) and almost nonfunctional OMF/AAF support (very slightly better n CS4).
