We’ve been working in Adobe Creative Design CS3 for a few years now and skipped CS4.  This past week we took the plunge and upgraded to Adobe Master Collection CS5.  Unlike the Design and/or Web Premium suites, the master collection has every single adobe product.  We’ve been using Dreamweaver, Fireworks, Photoshop, Illustrator and Flash for years, but the Master Suite has some very powerful products that we’ve never used before….most notably After Effects, which handles video production.  For the time being, we’ll stick to the new features of the programs we know, but it’s exciting to be up-to-date.
