I shoot raw + jpeg all the time. I have been using the raw files more frequently in the last year or so, as I've become more comfortable with and more knowledgeable of Adobe Camera Raw. Most, but not all, of my prints are from raw files. I tended to use jpegs for quicker processing when I wanted to post quickly to flickr and pbase.
Even if I were to use jpegs more frequently, I would still shoot raw + jpeg. There are some files which need the ability to get the extra detail in the highlights sometimes lost in jpegs. Also, raw converters have been improving, so it's sometimes possible to improve the results from an older file.
At this point, even if I were to abandon jpeg processing, I like the raw + jpeg combination, because I use Photo Mechanic to rename, edit and sometimes sort, and it works quicker and with bigger previews using the jpeg.
