Photoshop is still the preferred choice for me, I like the functionality and the colour correction capabilities this version has to offer making it better than ever before.  The interface has been slightly updated but nothing that really confused me, one of the big changes that I can really appreciate is the new workspace switcher which has a range of preset workspaces which is really handy for selecting window layouts.  A few of the other benefits that I think are a vast improvement include Bridge CS4 which is for asset management which has been significantly improved and is great – I really recommend having a look.  It is useful for me because I enjoy the better functionality you can achieve with altering photos with the powerful colour correction tools from Camera Raw 5.  For me the added benefits from Photoshop alone make this a worthwhile package.

Dreamweaver again is the industry recognised html editor of choice.  With this version they have continued to make working with related files easier and instantly accessible through the related files toolbar.  The new live view command makes layout view a full on browser, even more useful is the feature that allows you to see the code the browser is rendering as you interact with page.  Dreamweaver never ceases to impress me and has continued to make itself accessible for all levels of designers with its simple interface and design.  Dreamweaver has delivered again being miles ahead of its competitor.

Although I use Flash I don’t use it to its full capabilities, having only a little knowledge of ActionScript I can only really comment on the basic interface which only gets better having moved the properties panel to appear vertically this opens up much needed space for the handy timeline panel at the bottom which I always felt was cluttered and lost, they have also tried to encourage simple animation which I think can only benefit new Flash users.

All in all I think CS4 is great and well worth the investment it is not only new and improved, it opens doors for better integrated design for all levels.
