So one of the biggest reasons to upgrade or buy Photoshop CS5 is content aware fill. It's used to remove people, poles, cars, birds, etc. from your backgrounds quickly and easily. I have found that the success rate of clean removal of "problem" element to be about 30%, and the rest of the time you either cannot use it cause it causes more problems, or you get closer that with just a bit more work, get you reach your goal sooner rather than later. Well guess what. If you buy Photoshop Elements for $79, you get the feature. It works just as well, and you don't need to pay $299 for the upgrade in from CS4 to CS5. I'm actually a little disappointed in Adobe for this one. Too bad I already bought CS5.
It also has photomerge, which builds panoramas in a great way. It's strange that it is found here, but is not included in Lightroom 3 which costs $299. Hummm. . . .for $79, those of you that don't have photoshop, want to upgrade to CS5, or have lightrrom but want to do panoramas, you cannot beat the price.
