I would suggest there is a place for jpegs out of the camera - but it is a small, niche market and should be avoided wherever possible where IQ is important.
Can you try to stay on topic? This thread is supposed to be about how much the 5DIII sucks 
Sorry - that is where the 5DIII is better than the D800. I will sit on the naughty chair for 10 mins

I for one am excited about the OOC Jpeg possibilities. For the most part, I shoot 100% professionally and depending on my clients needs and wants, some are strictly for web, some are for print, some both... If going in I know the shots will be used for print or if I get that inkling that they are going to portfolio quality shots/products, then I shoot raw+jpeg... If it's going to be for web only, most photos are scaled down to 1/4 size roughly to fit internet screens (ecommerce) and such, screw it, jpeg... shooting kids running around the yard, jpegs... shooting for my personal enjoyment, jpeg, unless that is I see the possibility of it being portfolio quality, then raw + jpeg... Lets not fear the power of the jpeg.
