It won't replace my Oly E-520 but I want somethign I can have always with me to take pics. So far haven't seen a P&S I like that would offer RAWs.

Note I also do not code

Thanks for the support, of course if you use the Canon Hackers Development Kit(CHDK), any Canon point and shoot will shoot in 3 different formats of RAW

Is it because of the processing power? Or the file size (RAW files are much bigger than jpeg's)?

Luckily, N900 doesn't lack in any of them. It has both the muscle and the space. So, I hope it is possible to shoot RAW with N900.

Can someone provide some insight into this.

Point and shoots don't provide RAW files because very simply put, the vast majority of end users would have no idea what to do with them. They require advanced editing software to convert them or even view them in some cases, they take forever to write to the memory card, and they take up a lot of space. For the person who does *not* care about editing, raws are very nearly pointless.

I think it's mostly that most people don't care enough for RAWs. I tend to shot in both RAW+JPEG(at max quality) if I like the JPEG I'll keep it if not I'll try playing with the RAW to see if I can get anything out of it.

Quite right, RAW image files are after one curve and one levels have been applied, typically JPEGs have had 2 sets applied and therefore become more faulty to edit. RAWs also have non lossy or no compression at all. Making them the premier archival format.

On occasion I shoot professionally using Pentax DSLRs and I always, always, ALWAYS, shoot in RAW and convert to JPEG or TIFF later. I have probably close to 100gbs of RAW images saved on my external for safe keeping.

Now to make a long story short, with the right codec, which should easily be obtained for something like Adobe's DNG format, it should be a simple matter of saving the RAW image info to it.
