However, I wonder why, along with all the tools you cite, there is no mention made of the Gimp...? After all, it is available on Windows, Mac and Linux, it doesn't cost a dime, and it also includes:
- HDR effects (in script-fu): Tone Mapping and Exposure Blend
- painting effects (programmable brushes)
- GEGL (yes, 3D in Gimp)
- lens correction
Now, all of these aren't as advanced nor are they as easy to use as the Photoshop versions, but they are here and they work. For free.
Paint.NET, iPhoto, WL Photo Gallery are not exactly professional-grade applications - while the Gimp (with colour profile management capabilities, layers-based approach, programmable filters, vector graphics capabilities, advanced stylus management, etc.) is, actually, used by some professionals... And a direct competitor to Photoshop.
Thus why I found its absence (Paint.NET isn't quite there yet, it does have the merit of being free for use -but not open source- ) a bit surprising.
"Digital SLRs let you save files not just as JPEGs but in a RAW . . . "
So does my point and shoot from 2002 . . . and (I believe all new) Interchangeable Lens Digital Cameras, and lots of point and shoots available today. You could have just said "Many Digital Cameras" rather than implying that Digital SLRs do something that other cameras don't, which is not true.
Traciatim - true, but 1) the CS5 emphasis is very much on the DSLRs judging by the minimal list of cameras covered by the cusotm lens correction (and Adobe refers to only 275 cameras whose RAW formats are supported) and 2) my feeling is usually that point and shoot cameras with small lenses and sensors tend to need the in-camera processing to deliver good images
Photoshop is the ultimate consumer image editing tool. There are lesser tools sold by Adobe that will do for most people with digital cameras, and they are a lot less expensive- Photoshop Elements and Photoshop Lightroom. Of course Gimp and Irfanview are much cheaper options than that for the average person too.
If it was for sale for half-price $300, I doubt sales would double. The same universities and design companies would buy it, but it would still be out of many consumers' price range. At this price range, with spreading of costs the time saved and final quality of the product will justify the price.

I would argue that most point and shoots today do not offer RAW. And, most interchangeable lens cameras ARE DSLRs (not all).
The ruler trick has worked in Photoshop for as long as I remember, but it was obfuscated a little bit - there was no Straighten button, but if you draw a ruler along what should be a straight edge, then go to Image -> Image Rotation -> Arbitrary..., the ruler's angle will automatically be applied. Just click OK and your image is straightened. Works back at least as far as Photoshop 7.
The only new thing there is the "Straighten" button that saves you a few clicks.
@ Viewer: You are comparing apples & oranges. Corel is a vector image creation program used widely in graphic designing. Whereas Photoshop is an image editing software which is the industrial standard. Instead of vectors, it uses bitmaps.
Try editing an image in Corel by its histogram. You won't be able to, coz it doesn't exist in Corel! Also you' have to tear your hair apart if you try creating a high quality bitmap in Corel.
The usage for both is different.
