Thanks for the feedback. It's a tricky article because I wanted to help both the first-time photographers as well as the intermediate enthusiasts find their camera. It's about buying the right camera and then learning to use it appropriately.
The thing w/controlling DOF is that on today's 1.6 crop small-photosite designs, you not only have to deal with stopping down, but diffraction error that starts occuring when you stop down too much or something as simple as keeping the shutter high enough. For you and me, DOF is intuitive. Exposure compensation has become intuitive. A lot of people don't want to have to deal with DOF and exposure compensation though. They find enough creativity in the composition alone, and would rather just go with a pure point-and-shoot camera.
I ultimately left out a more detailed discussion about lenses and flashes for the DSLRs because I still feel that you can make your choice between digicam and SLR by assessing your creativity through interest in controlling DOF. If you just want a super telephoto and a bright flash, you should go with the Lumix FZ20 and a Vivitar 283/285. The f/2.8 lens on the Lumix is quite good, esp. with the on-camera post-processing and while ISO 100 on a digicam is closer to ISO400 on a DSLR, try finding a 400/5.6 IS for the price of the Lumix...
I don't believe in the media issue much. Flash cards are extremely affordable now w/512MB Ultra II's going for only $50. By the time you buy your "n+1" camera, prices will have dropped even further.
