Re: RAW vs. JPEG
My cameras shoot both, and as stated, memory and disc storage is inexpensive. So, I capture both. If it is a special picture, or if the exposure is a little bit off, I'll process the RAW, (usually captured in DNG format instead of the proprietary format). For web posting and snapshots, JPEGs are fine, assuming the exposure is accurate. For simple stuff, I use GIMP on Linux. For more difficult things, I'll use Photoshop, (it's wonderful getting an educational discount). The only reason I keep Windows on my machines is because of Photoshop.
