This is excellent advice. Buying a camera is easy and difficult for the same reason: they all work pretty well. For most of us, the difference between a cheap point-and-shoot and a fancy DSLR is actually rather small. The highest value is in having the camera with you, so it should be small and light. I used to use a bulky SLR in the days of film (a big brass Russian Zenit). It was fun and swapping lenses and filters around for different effects interesting. Now I have a compact digital with one lens (with zoom), and I take more photos.
If you want to leave some room to experiment with the technical stuff, get a camera with a good manual mode, so you can set the aperture, shutter speed, etc. But honestly, I use these for maybe one or two in every hundred photos. I enjoy letting the camera figure out those settings, so I can spend my effort in composing the shot.
I have a Lumix LX3 and love it, but there are many other good cameras out there. But as the parent says, make sure you hold a camera before buying it. Lots of menus are bad - you need to be able to find those buttons without even looking. And whatever you buy, practice with it lots.
