My best advice: <I>"If it ain't broke, don't fix it."</I>
If version 1.0 works fine for you, don't rush to upgrade. Take your time, and look around on lots of different websites for reviews. (Try searching Google). Most people on this site like Premiere, so version 2.0 may not get a review for a long time, if ever.
Also, your signature image breaks forum rules, so it's probably going to get removed. (Read the info on the site index page.)
