If you haven’t gotten your beta release of the new free Photoshop CS3 public beta yet, get it now (for Windows or Mac).  Wired has the scoop on the release.  Adobe has been more than generous with the Lightroom public betas.  However, I should warn you that I think Adobe is stringing us along like a crack dealer by giving us a free peek at the goods only to cut us off when we get addicted.  If you shoot RAW and haven’t tried Lightroom yet, you should.  It’s all I use for my RAW workflow and I know I’ll be shelling out the two or three hundred bones for the final release after the beta has expired.
