I would disagree with the term "DSLR craze" and I would also say that if you're happy with your current digital camera, then consider yourself fortunate and call it a day. (I think it's more important to be happy than to have the best of everything!) "Craze" sounds more like a fad, which I don't think is valid.
Things are really no different than they were before digital came along. The "average" photographer had a point-and-shoot camera using whatever type of film. If they craved more quality or more control over the photographs, they bought an SLR. Same thing with digital.
Some of the PnS and/or "bridge" cameras are very nice. However, DSLRs will offer more speed, quality, features, and primarily control over your pictures.
The "craze" is that DSLRs are finally getting to the point where the prices come close to the higher-end PnS cameras, and those of us who used an SLR in the 35mm days (even an old fully-manual one!) can finally make the step up to a digital SLR. There was a little bit of time there were a very nice DSLR was as cheap as $367 after a $100 rebate. Currently, I think you can find a Pentax, Nikon, or Canon in the $550-650 range. (I'm not sure what the cheapest Sony, Olympus, etc go for.)
The first thing is to do a little research on what an SLR is and decide if that's for you. IMHO, if you're not interested in playing with focus, exposure, depth of field, etc, you might be just as happy with a higher-end "bridge" point-n-shoot camera.
But, a DSLR will offer a better photo (don't be fooled by megapixel count, either - more megapixels does not automatically mean better picture, often the opposite) and room to grow.
For me, I was never happy with point-n-shoots and have always loved shooting with an SLR, so that's definitely best for me. But I don't think it's fair to automatically lump all PnS cameras into the junk pile or think less of someone who preserves the dimunitive size or simplicity of a PnS. This is not like DVD and VHS where VHS really was garbage and was quite rightly killed off by DVD - PnS digicams aren't going anywhere.
