Yes, and the environment works best for the sRGB color space. Wider gamuts are supported, but not for all features.

I own PSP X6 and have been very disappointed by its RAW converter. I don't want to dis the product, but my practice is to use it for Photoshop-type tasks and leave the basic photography PP for Lightroom.

Ahh....here is where things start getting interesting. You are essentially on the right track.- Picasa is OK for viewing, but sucks for RAW conversion and PP
- RAW data is never edited per se. Generally, the original RAW file is not overwritten*.
- The data in the DNG/PEF file is read and interpreted by the RAW converter for display. "Edits" may be then done in memory on the display image.
- Edits are saved either as a new file in a true image format (JPEG, TIFF, PNG, etc.) or as a set of instructions (meta data) detailing the edit steps
- For programs that save the edit steps (example: Lightroom), this may be as part of a larger catalog, a "side-car" file, or as metadata in a DNG derived from the original RAW file
- Eventual output from all RAW converters is a true image file such as JPEG or TIFF. Additional editing may be done on the outputted file. In Lightroom this is done as an image "export" where the editing steps are applied to the RAW data and the resultant image written to a new file.
Sound confusing? It really isn't. You shoot RAW in order to create JPEG or some other type of true image file. Simple as that.

* Lightroom has the option to "sync" the edit metadata to the file system in addition to writing to its catalog. If the original file is a DNG, that file is overwritten to include the edit information. The resulting "edited" DNG may then be shared and opened by other Adobe products that are able to interpret the metadata. While the new version of the file is the result of an edit of the metadata, the actual RAW data is untouched.

Here are the bullet points:- RAW will give you more flexibility with less potential for artifact in PP
- RAW files consume more space on the card than JPEG. That is the trade-off.
- I strongly endorse Adobe Lightroom for general photo post-processing
- A time-limited demo version of Lightroom is available for download
- The various open-source RAW converters (almost all of which are based on Dave Coffin's DCRaw) can do a credible job and are a good alternative to Lightroom
The first point is the big one for me. JPEG images have a fraction of the original data and data are what you work with in post processing. If you want the benefit of the camera's full dynamic range and color response, RAW is your best option.
